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.

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
connectors to make identification easier than relying on hostnames that
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.

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 b8e610a067 TUN-7065: Revert Ingress Rule check for named tunnel configurations
Named Tunnels can exist without Ingress rules (They would default to

starting since they do not need ingress rules.

Sudarsan Reddy d19da6767a TUN-7021: Fix proxy-dns not starting when cloudflared tunnel is run
This PR starts a separate server for proxy-dns if the configuration is
available. This fixes a problem on cloudflared not starting in proxy-dns
mode if the url flag (which isn't necessary for proxy-dns) is not
provided. Note: This is still being supported for legacy reasons and
since proxy-dns is not a tunnel and should not be part of the
cloudflared tunnel group of commands.

Sudarsan Reddy 99b3736cc7 TUN-6999: cloudflared should attempt other edge addresses before falling back on protocol
This PR does two things:
It changes how we fallback to a lower protocol: The current state
is to try connecting with a protocol. If it fails, fall back to a
lower protocol. And try connecting with that and so on. With this PR,
if we fail to connect with a protocol, we will try to connect to other
edge addresses first. Only if we fail to connect to those will we
fall back to a lower protocol.
It fixes a behaviour where if we fail to connect to an edge addr,
we keep re-trying the same address over and over again.
This PR now switches between edge addresses on subsequent connecton attempts.
Note that through these switches, it still respects the backoff time.
(We are connecting to a different edge, but this helps to not bombard an edge
address with connect requests if a particular edge addresses stops working).

João Oliveirinha e517242194 TUN-6995: Disable quick-tunnels spin up by default
Before this change when running cloudflare tunnel command without any
subcommand and without any additional flag, we would spin up a
QuickTunnel.

This is really a strange behaviour because we can easily create unwanted
tunnels and results in bad user experience.
This also has the side effect on putting more burden in our services
that are probably just mistakes.

This commit fixes that by requiring  user to specify the url command
flag.
Running cloudflared tunnel alone will result in an error message
instead.

Sudarsan Reddy 7dee179652 TUN-7004: Dont show local config dirs for remotely configured tuns
cloudflared shows possible directories for config files to be present if
it doesn't see one when starting up. For remotely configured files, it
may not be necessary to have a config file present. This PR looks to see
if a token flag was provided, and if yes, does not log this message.

Devin Carr cfef0e737f TUN-6720: Remove forcibly closing connection during reconnect signal
Previously allowing the reconnect signal forcibly close the connection

in the tunnel connection. Allowing the signal to return and provide
a context cancel to the connection provides a safer shutdown of the
tunnel for this test-only scenario.

For WARP routing the defaults for these new settings are 5 seconds for connect timeout and 30 seconds for keep-alive timeout. These values can be configured either remotely or locally. Local config lives under "warp-routing" section in config.yaml.

For websocket-based proxy, the defaults come from originConfig settings (either global or per-service) and use the same defaults as HTTP proxying.

This is a cherry-pick of 157f5d1412
followed by build/CI changes so that amd64/linux FIPS compliance is
provided by new/separate binaries/artifacts/packages.

The reasoning being that FIPS compliance places excessive requirements
in the encryption algorithms used for regular users that do not care
about that. This can cause cloudflared to reject HTTPS origins that
would otherwise be accepted without FIPS checks.

This way, by having separate binaries, existing ones remain as they
were, and only FIPS-needy users will opt-in to the new FIPS binaries.

 - If the connection is unused, it is already closed as soon as possible.
 - If the connection is still used, it is closed on the cloudflared configured grace-period.

Even if cloudflared does not close the connection by the grace-period time,
the edge will do so.
