When a new QuicConnection is being established for HTTP/3 and it fails, we block the remote authority and remember why. Any further attempt to connect to that authority gets failed with that reason for a while.
We shouldn't do that if the failure is because we decided to stop the attempt, i.e. we (timeout) or user cancelled the passed in token.

Discovered in stress test as they randomly cancel requests.

When a new QuicConnection is being established for HTTP/3 and it fails, we block the remote authority and remember why. Any further attempt to connect to that authority gets failed with that reason for a while.
We shouldn't do that if the failure is because we decided to stop the attempt, i.e. we (timeout) or user cancelled the passed in token.

Discovered in stress test as they randomly cancel requests.

Fixes#87957
