> If KeyPurgeRequest is replayed, we do not want to purge the keys which were created after the original purge request was received. This could happen if a key was deleted, purged and then created and deleted again. The the purge request was replayed, it would purge the key deleted after the original purge request was completed.
> Hence, to maintain idempotence, we should only purge those keys from DeletedKeys table that have updateID < transactionLogIndex of the request.
