WIP: KUDU-2048. consensus: only evict unresponsive nodes if remaining voters
are viable
This adds a heuristic to the leader when it is deciding whether to evict
an unresponsive node. It will now only do so if the remaining nodes
appear viable (i.e they have recently had a successful communication
with the leader).
WIP: trying to do some cleanup of the error tracking -- it seems that
consensus_queue.cc doesn't get any notification of when a follower is
getting 'connection refused' errors etc, which isn't great for this
heuristic. Posting to gerrit for a full test run.
