quic: adding upstream config (#15537)

Alas I didn't end up moving all of the protocol options over, as the cluster has its own timeout params so most of the QuicProtocolOptions are listener-specific.

Commit Message: adding quic protocol config to quic upstream
Risk Level: n/a (quic only)
Testing: unit tests
Docs Changes: n/a
Release Notes: n/a
part of #14829
