gfe-relnote: (n/a) Pluming work for loss detection tuning using go/smartchoices. No behavior change, not protected.

This adds 4 'broadcast' points to a quic session: SetLossDetectionTuner, OnMinRttAvailable, OnConfigNegotiated and OnConnectionClosed. Currently nothing is done at these points. The next CL will implement a loss detection tuner and use it from uStreamer.
