Connectivity metrics: add transports to connect stats

Browse Source 
This patch groups connect() events per netId. It adds netid and
transport information to serialized ConnectStatistics events.

Test: updated NetdEventListenerServiceTest
      updated IpConnectivityMetricsTest
      $ runtest frameworks-net passes
