[kudu-CR] KUDU-2230: the leader is always a viable voter

["Alexey Serbin (Code Review)" <ge...@cloudera.org>]

Hello Mike Percy, Kudu Jenkins, Andrew Wong, 

I'd like you to reexamine a change. Please visit

    http://gerrit.cloudera.org:8080/8709

to look at the new patch set (#4).

Change subject: KUDU-2230: the leader is always a viable voter

KUDU-2230: the leader is always a viable voter

While iterating over peers in PeerMessageQueue::SafeToEvictUnlocked(),
assume that the leader is always a viable voter.  Prior to this patch,
the leader itself was not counted as a viable voter since the leader
does not update its own last_communication_time.
