Monitoring the QUIC version used for sessions with successful handshake.

Internal context: a healthy Bonnet may only establish a new QUIC connection every a few hours (e.g. 10) while an unhealthy Bonnet experiencing 1-side black-hole can try to establish ~50 QUIC connections per hour. As a result, a small fraction of unhealthy Bonnets can potentially skew the types (IETF QUIC vs gQUIC) of QUIC sessions created at the server side. This CL adds metrics to log the types (IETF QUIC vs gQUIC) of QUIC sessions finishing handshake at the server side, which will reflect the QUIC versions used by healthy Bonnet.
