Change subject: KUDU-2443 moving single-replica tablets is broken ...................................................................... KUDU-2443 moving single-replica tablets is broken Fixed bug in the consensus::ShouldEvictReplica() function for the case when the leader replica of a tablet with replication factor of 1 (i.e. a non-replicated tablet) is marked with the REPLACE attribute and there is an extra voter replica in the tablet's Raft config. Prior to this fix, the master would try to evict the new extra voter from the configuration and then it would add a new non-voter because of the consensus::ShouldAddReplica() method's behavior. After the newly added non-voter replica catches up and is promoted to voter, that would happen again and again, until the REPLACE attribute is removed.
