## Summary
In order to make cloudflared behavior more predictable and
prevent an exhaustion of resources, we have decided to add
session limits that can be configured by the user. This first
commit introduces the session limiter and adds it to the UDP
handling path. For now the limiter is set to run only in
unlimited mode.
## 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.
