Devin Carr 44e6d1a313 TUN-8441: Correct UDP total sessions metric to a counter and add new ICMP metrics
cloudflared_udp_total_sessions was incorrectly a gauge when it
represents the total since the cloudflared process started and will
only ever increase.

Additionally adds new ICMP metrics for requests and replies.

Devin Carr 30197e7dfa TUN-8422: Add metrics for capnp method calls
Adds new suite of metrics to capture the following for capnp rpcs operations:
- Method calls
- Method call failures
- Method call latencies

Each of the operations is labeled by the handler that serves the method and
the method of operation invoked. Additionally, each of these are split
between if the operation was called by a client or served.

Devin Carr 654a326098 TUN-8424: Refactor capnp registration server
Move RegistrationServer and RegistrationClient into tunnelrpc module
to properly abstract out the capnp aspects internal to the module only.

Devin Carr 43446bc692 TUN-8423: Deprecate older legacy tunnel capnp interfaces
Since legacy tunnels have been removed for a while now, we can remove
many of the capnp rpc interfaces that are no longer leveraged by the
legacy tunnel registration and authentication mechanisms.

Devin Carr 8184bc457d TUN-8427: Fix BackoffHandler's internally shared clock structure
A clock structure was used to help support unit testing timetravel
but it is a globally shared object and is likely unsafe to share
across tests. Reordering of the tests seemed to have intermittent
failures for the TestWaitForBackoffFallback specifically on windows
builds.

Adjusting this to be a shim inside the BackoffHandler struct should
resolve shared object overrides in unit testing.

Additionally, added the reset retries functionality to be inline with
the ResetNow function of the BackoffHandler to align better with
expected functionality of the method.

Removes unused reconnectCredentialManager.

Devin Carr 2db00211f5 TUN-8419: Add capnp safe transport
To help support temporary errors that can occur in the capnp rpc
calls, a wrapper is introduced to inspect the error conditions and
allow for retrying within a short window.

Devin Carr eb2e4349e8 TUN-8415: Refactor capnp rpc into a single module
Combines the tunnelrpc and quic/schema capnp files into the same module.

To help reduce future issues with capnp id generation, capnpids are
provided in the capnp files from the existing capnp struct ids generated
in the go files.

Reduces the overall interface of the Capnp methods to the rest of
the code by providing an interface that will handle the quic protocol
selection.

Introduces a new `rpc-timeout` config that will allow all of the
SessionManager and ConfigurationManager RPC requests to have a timeout.
The timeout for these values is set to 5 seconds as non of these operations
for the managers should take a long time to complete.

Removed the RPC-specific logger as it never provided good debugging value
as the RPC method names were not visible in the logs.

Devin Carr 1b02d169ad TUN-8374: Close UDP socket if registration fails
If cloudflared was unable to register the UDP session with the
edge, the socket would be left open to be eventually closed by the
OS, or garbage collected by the runtime. Considering that either of
these closes happened significantly after some delay, it was causing
cloudflared to hold open file descriptors longer than usual if continuously
unable to register sessions.

João "Pisco" Fernandes 84833011ec TUN-8371: Bump quic-go to v0.42.0
## Summary
We discovered that we were being impacted by a bug in quic-go,
that could create deadlocks and not close connections.

This commit bumps quic-go to the version that contains the fix
to prevent that from happening.

GoncaloGarcia 86476e6248 TUN-8281: Run cloudflared query list tunnels/routes endpoint in a paginated way
Before this commit the commands that listed tunnels and tunnel routes would be limited to 1000 results by the server.

Now, the commands will call the endpoints until the result set is exhausted. This can take a long time if there are
thousands of pages available, since each request is executed synchronously.
From a user's perspective, nothing changes.

João "Pisco" Fernandes da6fac4133 TUN-8297: Improve write timeout logging on safe_stream.go
## Summary:
In order to properly monitor what is happening with the new write timeouts that we introduced
in TUN-8244 we need proper logging. Right now we were logging write timeouts when the safe
stream was being closed which didn't make sense because it was miss leading, so this commit
prevents that by adding a flag that allows us to know whether we are closing the stream or not.

João "Pisco" Fernandes 4f7165530c TUN-8275: Skip write timeout log on "no network activity"
## Summary
To avoid having to verbose logs we need to only log when an
actual issue occurred. Therefore, we will be skipping any error
logging if the write timeout is caused by no network activity
which just means that nothing is being sent through the stream.

This commit makes the remote diagnostics enabled by default, which is

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.
