## 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.
## 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
a useful feature when debugging cloudflared issues without manual intervention from users.
Users can still opt-out by disabling the feature flag.
Propagates the logger context into further locations to help provide more context for certain errors. For instance, upstream and downstream copying errors will properly have the assigned flow id attached and destination address.
## 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.
During the recent changes to the build pipeline, the implicit GOARM env variable changed from
6 to 7.
This means we need to explicitly define the GOARM to v6.
## Summary
We have decided to no longer push cloudflared to cloudflare homebrew, and use
the automation from homebrew-core to update cloudflared on their repository.
Therefore, the scripts for homebrew and makefile targets are no longer necessary.
Also update golang.org/x/net and google.golang.org/grpc to fix vulnerabilities,
although cloudflared is using them in a way that is not exposed to those risks
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.
