QUIC - Persist MRU 200 server's srtt (smoothed_rtt) of ServerNetworkStats

to disk.

+ Converted ServerNetworkStatsMap to MRUCache.
+ Renamed "NetworkStats" to "ServerNetworkStats" and made
  it a top level struct.
+ Didn't persist QuicBandwidth (bandwidth_estimate) because
  it is not being used
+ Deleted unnecessary net:: prefixes.
+ Ran "git cl format net".
