João Oliveirinha 5344a0bc6a TUN-8242: Enable remote diagnostics by default
This commit makes the remote diagnostics enabled by default, which is
a useful feature when debugging cloudflared issues without manual intervention from users.
Users can still opt-out by disabling the feature flag.

João "Pisco" Fernandes 76badfa01b TUN-8236: Add write timeout to quic and tcp connections
## Summary
To prevent bad eyeballs and severs to be able to exhaust the quic
control flows we are adding the possibility of having a timeout
for a write operation to be acknowledged. This will prevent hanging
connections from exhausting the quic control flows, creating a DDoS.

Use CLI context when running tunnel (#597)
When embedding the tunnel command inside another CLI, it
became difficult to test shutdown behavior due to this leaking
tunnel. By using the command context, we're able to shutdown
gracefully.

This changes guarantees that the coommand to report rule matches when

This is to be consistent with the 0-based indexing on the log lines when
proxying requests.

João "Pisco" Fernandes 541c63d737 TUN-7824: Fix usage of systemctl status to detect which services are installed
## Summary
To determine which services were installed, cloudflared, was using the command
`systemctl status` this command gives an error if the service is installed
but isn't running, which makes the `uninstall services` command report wrongly
the services not installed. Therefore, this commit adapts it to use the
`systemctl list-units` command combined with a grep to find which services are
installed and need to be removed.

João "Pisco" Fernandes 958b6f1d24 TUN-7813: Improve tunnel delete command to use cascade delete
## Summary
Previously the force flag in the tunnel delete command was only explicitly deleting the
connections of a tunnel. Therefore, we are changing it to use the cascade query parameter
supported by the API. That parameter will delegate to the server the deletion of the tunnel
dependencies implicitly instead of the client doing it explicitly. This means that not only
the connections will get deleted, but also the tunnel routes, ensuring that no dependencies
are left without a non-deleted tunnel.

João Oliveirinha 6d1d91d9f9 TUN-7787: Refactor cloudflared to use new route endpoints based on route IDs
This commits makes sure that cloudflared starts using the new API
endpoints for managing routes.

Additionally, the delete route operation still allows deleting by CIDR
and VNet but it is being marked as deprecated in favor of specifying the
route ID.

The goal of this change is to make it simpler for the user to delete
routes without specifying Vnet.

João "Pisco" Fernandes af3a66d60e TUN-7597: Add flag to disable auto-update services to be installed
Summary:
This commit adds a new flag "no-update-service" to the `cloudflared service install` command.

Previously, when installing cloudflared as a linux service it would always get auto-updates, now with this new flag it is possible to disable the auto updates of the service.

This flag allows to define whether we want cloudflared service to **perform auto updates or not**.
For **systemd this is done by removing the installation of the update service and timer**, for **sysv** this is done by **setting the cloudflared autoupdate flag**.

João Oliveirinha 0c8bc56930 TUN-7575: Add option to disable PTMU discovery over QUIC
This commit implements the option to disable PTMU discovery for QUIC
connections.
QUIC finds the PMTU during startup by increasing Ping packet frames
until Ping responses are not received anymore, and it seems to stick
with that PMTU forever.

This is no problem if the PTMU doesn't change over time, but if it does
it may case packet drops.
We add this hidden flag for debugging purposes in such situations as a
quick way to validate if problems that are being seen can be solved by
reducing the packet size to the edge.

Note however, that this option may impact UDP proxying since we expect
being able to send UDP packets of 1280 bytes over QUIC.
So, this option should not be used when tunnel is being used for UDP
proxying.

Devin Carr 8a3eade6d3 TUN-7553: Add flag to enable management diagnostic services
With the new flag --management-diagnostics (an opt-in flag)
cloudflared's will be able to report additional diagnostic information
over the management.argotunnel.com request path.
Additions include the /metrics prometheus endpoint; which is already
bound to a local port via --metrics.
/debug/pprof/(goroutine|heap) are also provided to allow for remotely
retrieving heap information from a running cloudflared connector.

Devin Carr 2b4815a9f5 TUN-7543: Add --debug-stream flag to cloudflared access ssh
Allows for debugging the payloads that are sent in client mode to
the ssh server. Required to be run with --log-directory to capture
logging output. Additionally has maximum limit that is provided with
the flag that will only capture the first N number of reads plus
writes through the WebSocket stream. These reads/writes are not directly
captured at the packet boundary so some reconstruction from the
log messages will be required.

Added User-Agent for all out-going cloudflared access
tcp requests in client mode.
Added check to not run terminal logging in cloudflared access tcp
client mode to not obstruct the stdin and stdout.

Sudarsan Reddy 1abd22ef0a TUN-7480: Added a timeout for unregisterUDP.
I deliberately kept this as an unregistertimeout because that was the
intent. In the future we could change this to a UDPConnConfig if we want
to pass multiple values here.

The idea of this PR is simply to add a configurable unregister UDP
timeout.

Sudarsan Reddy e426693330 TUN-7361: Add a label to override hostname
It might make sense for users to sometimes name their cloudflared

TUN-7360 provides. This PR provides a new --label option to cloudflared
tunnel that a user could provide to give custom names to their
connectors.

James Royal 171d4ac77c AUTH-3122 Verify that Access tokens are still valid in curl command
Before this change, the only sure fire way to make sure you had a valid
Access token was to run `cloudflared access login <your domain>`. That
was because that command would actually make a preflight request to ensure
that the edge considered that token valid. The most common reasons a token
was no longer valid was expiration and revocation. Expiration is easy to
check client side, but revocation can only be checked at the edge.

This change adds the same flow that cfd access login did to the curl command.
It will preflight the request with the token and ensure that the edge thinks
its valid before making the real request.

Sudarsan Reddy 5e212a6bf3 TUN-7360: Add Get Host Details handler in management service
With the management tunnels work, we allow calls to our edge service
   using an access JWT provided by Tunnelstore. Given a connector ID,
   this request is then proxied to the appropriate Cloudflare Tunnel.

   This PR takes advantage of this flow and adds a new host_details
   endpoint. Calls to this endpoint will result in cloudflared gathering
   some details about the host: hostname (os.hostname()) and ip address
   (localAddr in a dial).

   Note that the mini spec lists 4 alternatives and this picks alternative
   3 because:

   1. Ease of implementation: This is quick and non-intrusive to any of our
      code path. We expect to change how connection tracking works and
      regardless of the direction we take, it may be easy to keep, morph
      or throw this away.

   2. The cloudflared part of this round trip takes some time with a
      hostname call and a dial. But note that this is off the critical path
      and not an API that will be exercised often.

Devin Carr b89c092c1b TUN-7134: Acquire token for cloudflared tail
cloudflared tail will now fetch the management token from by making
a request to the Cloudflare API using the cert.pem (acquired from
cloudflared login).

Refactored some of the credentials code into it's own package as
to allow for easier use between subcommands outside of
`cloudflared tunnel`.

Sudarsan Reddy 5dbf76a7aa TUN-7335: Fix cloudflared update not working in windows
This PR fixes some long standing bugs in the windows update
paths. We previously did not surface the errors at all leading to
this function failing silently.

This PR:

1. Now returns the ExitError if the bat run for update fails.
2. Fixes the errors surfaced by that return:
    a. The batch file doesnt play well with spaces. This is fixed by
    using PROGRA~1/2 which are aliases windows uses.
    b. The existing script also seemed to be irregular about where batch
    files were put and looked for. This is also fixed in this script.
