KUDU-871. Support tombstoned voting

This patch makes it possible for tombstoned tablet replicas to vote in
Raft elections.

Changes:

* Add Stop() method to TabletReplica + Consensus lifecycle.
  * Includes new STOPPED state.
  * Tombstoning a replica should call Stop().
  * Deleting a replica should call Shutdown().
* Add positive and negative tests for tombstoned voting.
* Add a stress test that induces lots of tombstoned voting
  while running TabletCopy, TabletBootstrap, and DeleteTablet.
* Protect TabletMetadata::tombstone_last_logged_opid_ with a lock.
* Fix DeleteTableITest.TestMergeConsensusMetadata after tombstoned
  voting changed its assumption that tombstoned tablets would not vote.
* Fix several tests that expected tombstoned tablets to be SHUTDOWN when
  now they are STOPPED.
