Change subject: KUDU-1613: evict replicas with wrong server UUIDs ...................................................................... KUDU-1613: evict replicas with wrong server UUIDs Currently, if a tablet server is wiped and restarted at the same host and port with a new UUID assigned to it before the replicas on its previous incarnation are evicted, those replicas won't ever be evicted. With this patch, upon receiving a response with WRONG_SERVER_UUID, leaders will treat the follower as failed and handle it appropriately, re-replicating them elsewhere. A new test case is added to raft_consensus-itest that is set up to prompt eviction (i.e. low timeouts, ample servers to replicate to), and without the change, this test fails.
