raft: stableTo checks term matching
...
stableTo should only mark the index stable if the term is matched. After raft sends out unstable
entries to application, raft makes progress without waiting for reply. When the appliaction
calls the stableTo to notify the entries up to "index" are stable, raft might have truncated
some entries before "index" due to leader lost. raft must verify the (index,term) of stableTo,
before marking the entries as stable.

Travis is rather slow, and it may fail to listen on that port sometimes.

A MsgAppResp with Reject set should be sent back to the leader as soon
as possible instead of batching.

It should ignore the compact operation instead of panic because the case that
the log is restored from snapshot before executing compact is reasonable.

etcdserver: truncate WAL from correct index when forcing new cluster
...
When loading from a backup with a snapshot and WAL, the length of WAL entries
can be lower than the current index integer value, causing a panic when
slicing off uncommitted entries. This looks for WAL entries higher than
the current index before slicing.

Snapshot on raft storage should always succeed. If there is an error, it must
