> When appendEntries timeout, GRpcLogAppender has already updated
> lastRpcSendTime so that the next heartbeat may not be sent
> immediately.
> This problem is observed in RATIS-227.  The killed follower in
> testBasicAppendEntriesWithAllReplication may start a leader election
> after it has been restarted.
