f17c038fc4 etcdserver: api/v2v3: add initial tests 
Add a bunch of tests on fundamental operation of Create/Set/Delete.

Context: I want to use this package to run the discovery service against
the v3 storage backend. The limited functionality already implemented
should be sufficient to do this.

7b1ef37054 etcdserver/api/rafthttp: probe all Raft messages' RTT 
This PR adds another probing routine to monitor the connection
for Raft message transports. Previously, we only monitored
snapshot transports.

In our production cluster, we found one TCP connection had >8-sec
latencies to a remote peer, but "etcd_network_peer_round_trip_time_seconds"
metrics shows <1-sec latency distribution, which means etcd server
was not sampling enough while such latency spikes happen
outside of snapshot pipeline connection.
