TUN-8701: Simplify flow registration logs for datagram v3

To help reduce the volume of logs during the happy path of flow registration, there will only be one log message reported when a flow is completed.

There are additional fields added to all flow log messages:
1. `src`: local address
2. `dst`: origin address
3. `durationMS`: capturing the total duration of the flow in milliseconds

Additional logs were added to capture when a flow was migrated or when cloudflared sent off a registration response retry.

Closes TUN-8701

+## 2024.10.0
+### Bug Fixes
+- We fixed a bug related to `--grace-period`. Tunnels that use QUIC as transport weren't abiding by this waiting period before forcefully closing the connections to the edge. From now on, both QUIC and HTTP2 tunnels will wait for either the grace period to end (defaults to 30 seconds) or until the last in-flight request is handled. Users that wish to maintain the previous behavior should set `--grace-period` to 0 if `--protocol` is set to `quic`. This will force `cloudflared` to shutdown as soon as either SIGTERM or SIGINT is received.
+
+## 2024.2.1
+### Notices
+- Starting from this version, tunnel diagnostics will be enabled by default. This will allow the engineering team to remotely get diagnostics from cloudflared during debug activities. Users still have the capability to opt-out of this feature by defining `--management-diagnostics=false` (or env `TUNNEL_MANAGEMENT_DIAGNOSTICS`).
+
+## 2023.9.0
+### Notices
+- The `warp-routing` `enabled: boolean` flag is no longer supported in the configuration file. Warp Routing traffic (eg TCP, UDP, ICMP) traffic is proxied to cloudflared if routes to the target tunnel are configured. This change does not affect remotely managed tunnels, but for locally managed tunnels, users that might be relying on this feature flag to block traffic should instead guarantee that tunnel has no Private Routes configured for the tunnel.
+## 2023.7.0
+### New Features
+- You can now enable additional diagnostics over the management.argotunnel.com service for your active cloudflared connectors via a new runtime flag `--management-diagnostics` (or env `TUNNEL_MANAGEMENT_DIAGNOSTICS`). This feature is provided as opt-in and requires the flag to enable. Endpoints such as /metrics provides your prometheus metrics endpoint another mechanism to be reached. Additionally /debug/pprof/(goroutine|heap) are also introduced to allow for remotely retrieving active pprof information from a running cloudflared connector.
+
+## 2023.4.1
+### New Features
+- You can now stream your logs from your remote cloudflared to your local terminal with `cloudflared tail <TUNNEL-ID>`. This new feature requires the remote cloudflared to be version 2023.4.1 or higher.
+
+## 2023.3.2
+### Notices
+- Due to the nature of QuickTunnels (https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/do-more-with-tunnels/trycloudflare/) and its intended usage for testing and experiment of Cloudflare Tunnels, starting from 2023.3.2, QuickTunnels only make a single connection to the edge. If users want to use Tunnels in a production environment, they should move to Named Tunnels instead. (https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/remote/#set-up-a-tunnel-remotely-dashboard-setup)
+
+## 2023.3.1
+### Breaking Change
+- Running a tunnel without ingress rules defined in configuration file nor from the CLI flags will no longer provide a default ingress rule to localhost:8080 and instead will return HTTP response code 503 for all incoming HTTP requests.
+
+### Security Fixes
+- Windows 32 bit machines MSI now defaults to Program Files to install cloudflared. (See CVE-2023-1314). The cloudflared client itself is unaffected. This just changes how the installer works on 32 bit windows machines.
+
+### Bug Fixes
+- Fixed a bug that would cause running tunnel on Bastion mode and without ingress rules to crash.
+
+## 2023.2.2
+### Notices
+- Legacy tunnels were officially deprecated on December 1, 2022. Starting with this version, cloudflared no longer supports connecting legacy tunnels.
+- h2mux tunnel connection protocol is no longer supported. Any tunnels still configured to use this protocol will alert and use http2 tunnel protocol instead. We recommend using quic protocol for all tunnels going forward.
+
+## 2023.2.1
+### Bug fixes
+- Fixed a bug in TCP connection proxy that could result in the connection being closed before all data was written.
+- cloudflared now correctly aborts body write if connection to origin service fails after response headers were sent already.
+- Fixed a bug introduced in the previous release where debug endpoints were removed.
+
+## 2022.12.0
+### Improvements
+- cloudflared now attempts to try other edge addresses before falling back to a lower protocol.
+- cloudflared tunnel no longer spins up a quick tunnel. The call has to be explicit and provide a --url flag.
+- cloudflared will now randomly pick the first or second region to connect to instead of always connecting to region2 first.
+
+## 2022.9.0
+### New Features
+- cloudflared now rejects ingress rules with invalid http status codes for http_status.
+
+## 2022.8.1
+### New Features
+- cloudflared now remembers if it connected to a certain protocol successfully. If it did, it does not fall back to a lower
+  protocol on connection failures.
+
+## 2022.7.1
+### New Features
+- It is now possible to connect cloudflared tunnel to Cloudflare Global Network with IPv6. See `cloudflared tunnel --help` and look for `edge-ip-version` for more information. For now, the default behavior is to still connect with IPv4 only.
+
+### Bug Fixes
+- Several bug fixes related with QUIC transport (used between cloudflared tunnel and Cloudflare Global Network). Updating to this version is highly recommended.
+
+## 2022.4.0
+### Bug Fixes
+- `cloudflared tunnel run` no longer logs the Tunnel token or JSON credentials in clear text as those are the secret
+that allows to run the Tunnel.
+
+## 2022.3.4
+### New Features
+- It is now possible to retrieve the credentials that allow to run a Tunnel in case you forgot/lost them. This is
+achievable with: `cloudflared tunnel token --cred-file /path/to/file.json TUNNEL`. This new feature only works for
+Tunnels created with cloudflared version 2022.3.0 or more recent.
+
+### Bug Fixes
+- `cloudflared service install` now starts the underlying agent service on Linux operating system (similarly to the
+behaviour in Windows and MacOS).
+
+## 2022.3.3
+### Bug Fixes
+- `cloudflared service install` now starts the underlying agent service on Windows operating system (similarly to the
+behaviour in MacOS).
+
+## 2022.3.1
+### Bug Fixes
+- Various fixes to the reliability of `quic` protocol, including an edge case that could lead to cloudflared crashing.
+
+## 2022.3.0
+### New Features
+- It is now possible to configure Ingress Rules to point to an origin served by unix socket with either HTTP or HTTPS.
+If the origin starts with `unix:/` then we assume HTTP (existing behavior). Otherwise, the origin can start with
+`unix+tls:/` for HTTPS.
+
+## 2022.2.1
+### New Features
+- This project now has a new LICENSE that is more compliant with open source purposes.
+
+### Bug Fixes
+- Various fixes to the reliability of `quic` protocol.
+
+## 2022.1.3
+### New Features
+- New `cloudflared tunnel vnet` commands to allow for private routing to be virtualized. This means that the same CIDR
+can now be used to point to two different Tunnels with `cloudflared tunnel route ip` command. More information will be
+made available on blog.cloudflare.com and developers.cloudflare.com/cloudflare-one once the feature is globally available.
+
+### Bug Fixes
+- Correctly handle proxying UDP datagrams with no payload.
+- Bug fix for origins that use Server-Sent Events (SSE).
+
+## 2022.1.0
+### Improvements
+- If a specific `protocol` property is defined (e.g. for `quic`), cloudflared no longer falls back to an older protocol
+(such as `http2`) in face of connectivity errors. This is important because some features are only supported in a specific
+protocol (e.g. UDP proxying only works for `quic`). Hence, if a user chooses a protocol, cloudflared now adheres to it
+no matter what.
+
+### Bug Fixes
+- Stopping cloudflared running with `quic` protocol now respects graceful shutdown.
+
+## 2021.12.2
+### Bug Fixes
+- Fix logging when `quic` transport is used and UDP traffic is proxied.
+- FIPS compliant cloudflared binaries will now be released as separate artifacts. Recall that these are only for linux
+and amd64.
+
+## 2021.12.1
+### Bug Fixes
+ - Fixes Github issue #530 where cloudflared 2021.12.0 could not reach origins that were HTTPS and using certain encryption
+methods forbidden by FIPS compliance (such as Let's Encrypt certificates). To address this fix we have temporarily reverted
+FIPS compliance from amd64 linux binaries that was recently introduced (or fixed actually as it was never working before).
+
+## 2021.12.0
+### New Features
+- Cloudflared binary released for amd64 linux is now FIPS compliant.
+
+### Improvements
+- Logging about connectivity to Cloudflare edge now only yields `ERR` level logging if there are no connections to
+Cloudflare edge that are active. Otherwise it logs `WARN` level.
+ 
+### Bug Fixes
+- Fixes Github issue #501.
+
+## 2021.11.0
+### Improvements
+- Fallback from `protocol:quic` to `protocol:http2` immediately if UDP connectivity isn't available. This could be because of a firewall or 
+egress rule.
+
+## 2021.10.4
+### Improvements
+- Collect quic transport metrics on RTT, packets and bytes transferred.
+
+### Bug Fixes
+- Fix race condition that was writing to the connection after the http2 handler returns.
+
+## 2021.9.2
+
+### New features
+- `cloudflared` can now run with `quic` as the underlying tunnel transport protocol. To try it, change or add "protocol: quic" to your config.yml file or
+run cloudflared with the `--protocol quic` flag. e.g:
+    `cloudflared tunnel --protocol quic run <tunnel-name>`
+
+### Bug Fixes
+- Fixed some generic transport bugs in `quic` mode. It's advised to upgrade to at least this version (2021.9.2) when running `cloudflared`
+with `quic` protocol.
+- `cloudflared` docker images will now show version.
+
+
+## 2021.8.4
+### Improvements
+- Temporary tunnels (those hosted on trycloudflare.com that do not require a Cloudflare login) now run as Named Tunnels
+underneath. We recall that these tunnels should not be relied upon for production usage as they come with no guarantee
+of uptime. Previous cloudflared versions will soon be unable to run legacy temporary tunnels and will require an update
+(to this version or more recent).
+
+## 2021.8.2
+### Improvements
+- Because Equinox os shutting down, all cloudflared releases are now present [here](https://github.com/cloudflare/cloudflared/releases).
+[Equinox](https://dl.equinox.io/cloudflare/cloudflared/stable) will no longer receive updates. 
+
+## 2021.8.0
+### Bug fixes
+- Prevents tunnel from accidentally running when only proxy-dns should run. 
+
+### Improvements
+- If auto protocol transport lookup fails, we now default to a transport instead of not connecting.
+
+## 2021.6.0
+### Bug Fixes
+- Fixes a http2 transport (the new default for Named Tunnels) to work with unix socket origins.
+
+
+## 2021.5.10
+### Bug Fixes
+- Fixes a memory leak in h2mux transport that connects cloudflared to Cloudflare edge.
+
+
+## 2021.5.9
+### New Features
+- Uses new Worker based login helper service to facilitate token exchange in cloudflared flows.
+
+### Bug Fixes
+- Fixes Centos-7 builds.
+
+## 2021.5.8
+### New Features
+- When creating a DNS record to point a hostname at a tunnel, you can now use --overwrite-dns to overwrite any existing
+  DNS records with that hostname. This works both when using the CLI to provision DNS, as well as when starting an adhoc
+  named tunnel, e.g.:
+  - `cloudflared tunnel route dns --overwrite-dns foo-tunnel foo.example.com`
+  - `cloudflared tunnel --overwrite-dns --name foo-tunnel --hostname foo.example.com`
+
+## 2021.5.7
+### New Features
+- Named Tunnels will automatically select the protocol to connect to Cloudflare's edge network.
+
+## 2021.5.0
+
+### New Features
+- It is now possible to run the same tunnel using more than one `cloudflared` instance. This is a server-side change and
+  is compatible with any client version that uses Named Tunnels.
+
+  To get started, visit our [developer documentation](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/run-tunnel/deploy-cloudflared-replicas).
+- `cloudflared tunnel ingress validate` will now warn about unused keys in your config file. This is helpful for
+  detecting typos in your config.
+- If `cloudflared` detects it is running inside a Linux container, it will limit itself to use only the number of CPUs
+  the pod has been granted, instead of trying to use every CPU available.
+
+## 2021.4.0
+
+### Bug Fixes
+
+- Fixed proxying of websocket requests to avoid possibility of losing initial frames that were sent in the same TCP
+  packet as response headers [#345](https://github.com/cloudflare/cloudflared/issues/345).
+- `proxy-dns` option now works in conjunction with running a named tunnel [#346](https://github.com/cloudflare/cloudflared/issues/346).
+
+## 2021.3.6
+
+### Bug Fixes
+
+- Reverted 2021.3.5 improvement to use HTTP/2 in a best-effort manner between cloudflared and origin services because
+  it was found to break in some cases.
+
+## 2021.3.5
+
+### Improvements
+
+ - HTTP/2 transport is now always chosen if origin server supports it and the service url scheme is HTTPS.
+   This was previously done in a best attempt manner.
+
+### Bug Fixes
+
+ - The MacOS binaries were not successfully released in 2021.3.3 and 2021.3.4. This release is aimed at addressing that.
+
+## 2021.3.3
+
+### Improvements
+
+- Tunnel create command, as well as, running ad-hoc tunnels using `cloudflared tunnel -name NAME`, will not overwrite
+  existing files when writing tunnel credentials.
+
+### Bug Fixes
+
+- Tunnel create and delete commands no longer use path to credentials from the configuration file.
+  If you need ot place tunnel credentials file at a specific location, you must use `--credentials-file` flag.
+- Access ssh-gen creates properly named keys for SSH short lived certs.
+
+
+## 2021.3.2
+
+### New Features
+
+- It is now possible to obtain more detailed information about the cloudflared connectors to Cloudflare Edge via
+  `cloudflared tunnel info <name/uuid>`. It is possible to sort the output as well as output in different formats,
+  such as: `cloudflared tunnel info --sort-by version --invert-sort --output json <name/uuid>`.
+  You can obtain more information via `cloudflared tunnel info --help`.
+
+### Bug Fixes
+
+- Don't look for configuration file in default paths when `--config FILE` flag is present after `tunnel` subcommand.
+- cloudflared access token command now functions correctly with the new token-per-app change from 2021.3.0.
+
+
+## 2021.3.0
+
+### New Features
+
+- [Cloudflare One Routing](https://developers.cloudflare.com/cloudflare-one/tutorials/warp-to-tunnel) specific commands
+  now show up in the `cloudflared tunnel route --help` output.
+- There is a new ingress type that allows cloudflared to proxy SOCKS5 as a bastion. You can use it with an ingress
+  rule by adding `service: socks-proxy`. Traffic is routed to any destination specified by the SOCKS5 packet but only
+  if allowed by a rule. In the following example we allow proxying to a certain CIDR but explicitly forbid one address
+  within it:
+```
+ingress:
+  - hostname: socks.example.com
+    service: socks-proxy
+    originRequest:
+      ipRules:
+        - prefix: 192.168.1.8/32
+          allow: false
+        - prefix: 192.168.1.0/24
+          ports: [80, 443]
+          allow: true
+```
+
+
+### Improvements
+
+- Nested commands, such as `cloudflared tunnel run`, now consider CLI arguments even if they appear earlier on the
+  command. For instance, `cloudflared --config config.yaml tunnel run` will now behave the same as
+  `cloudflared tunnel --config config.yaml run`
+- Warnings are now shown in the output logs whenever cloudflared is running without the most recent version and
+  `no-autoupdate` is `true`.
+- Access tokens are now stored per Access App instead of per request path. This decreases the number of times that the
+  user is required to authenticate with an Access policy redundantly.
+
+### Bug Fixes
+
+- GitHub [PR #317](https://github.com/cloudflare/cloudflared/issues/317) was broken in 2021.2.5 and is now fixed again.
+
+## 2021.2.5
+
+### New Features
+
+- We introduce [Cloudflare One Routing](https://developers.cloudflare.com/cloudflare-one/tutorials/warp-to-tunnel) in
+  beta mode. Cloudflare customer can now connect users and private networks with RFC 1918 IP addresses via the
+  Cloudflare edge network. Users running Cloudflare WARP client in the same organization can connect to the services
+  made available by Argo Tunnel IP routes. Please share your feedback in the GitHub issue tracker.
+
+## 2021.2.4
+
+### Bug Fixes
+
+- Reverts the Improvement released in 2021.2.3 for CLI arguments as it introduced a regression where cloudflared failed
+  to read URLs in configuration files.
+- cloudflared now logs the reason for failed connections if the error is recoverable.
+
+## 2021.2.3
+
+### Backward Incompatible Changes
+
+- Removes db-connect. The Cloudflare Workers product will continue to support db-connect implementations with versions
+  of cloudflared that predate this release and include support for db-connect.
+
+### New Features
+
+- Introduces support for proxy configurations with websockets in arbitrary TCP connections (#318).
+
+### Improvements
+
+- (reverted) Nested command line argument handling.
+
+### Bug Fixes
+
+- The maximum number of upstream connections is now limited by default which should fix reported issues of cloudflared
+  exhausting CPU usage when faced with connectivity issues.

+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
 
-5.3	Governing Law.  This Agreement shall be governed by the laws of the State
-of California, USA, excluding conflict of laws and provisions, and excluding the
-United Nations Convention on Contracts for the International Sale of Goods.
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and

-representative of the other for any purpose and neither shall have any right,

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
 
-5.6	Severability.  If any provision of this Agreement is held by a court of
-competent jurisdiction to be contrary to law, such provision shall be changed
-and interpreted so as to best accomplish the objectives of the original
-provision to the fullest extent allowed by law and the remaining provisions of
-this Agreement shall remain in full force and effect.
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
 
-5.7	Force Majeure.  CloudFlare shall not be liable to the other party for any
-failure or delay in performance caused by reasons beyond its reasonable control.
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
 
-5.8	Complete Understanding.  This Agreement and the Related Agreement
-constitute the final, complete and exclusive agreement between the parties with
-respect to the subject matter hereof, and supersedes all previous written and
-oral agreements and communications related to the subject matter of this
-Agreement.  To the extent this Agreement and the Related Agreement conflict,
-this Agreement shall control.
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Contains the command-line client for Cloudflare Tunnel, a tunneling daemon that proxies traffic from the Cloudflare network to your origins.
+This daemon sits between Cloudflare network and your origin (e.g. a webserver). Cloudflare attracts client requests and sends them to you
+via this daemon, without requiring you to poke holes on your firewall --- your origin can remain as closed as possible.
+Extensive documentation can be found in the [Cloudflare Tunnel section](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps) of the Cloudflare Docs.
+All usages related with proxying to your origins are available under `cloudflared tunnel help`.
+
+You can also use `cloudflared` to access Tunnel origins (that are protected with `cloudflared tunnel`) for TCP traffic
+at Layer 4 (i.e., not HTTP/websocket), which is relevant for use cases such as SSH, RDP, etc.
+Such usages are available under `cloudflared access help`.
+
+You can instead use [WARP client](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/configuration/private-networks)
+to access private origins behind Tunnels for Layer 4 traffic without requiring `cloudflared access` commands on the client side.
