Change subject: KUDU-3486 Periodically send tombstoned replica report to delete it. ...................................................................... KUDU-3486 Periodically send tombstoned replica report to delete it. A tombstoned tablet replica might never be deleted since the delete-type deletion could only occur when the tablet is deleted. And the requests will only be sent to the voters, not including the tombstoned ones. The data of tombstone replica is deleted, but metadata is persisted in memory, which will occupy a lot of memory, especially for the tablets with big SchemaPB. Tombstoned replicas can be deleted while processing heartbeats. So making the tservers periodically send some reports with tombstoned replicas will delete the useless tombstoned replicas. See KUDU-3486 for details.
