AUTO 587: BusyLockError mitigation - reclaiming lock

Due to possibly timing issue in Cass, sometimes delete row on quorum is missed causing lock to be held until TTL (that was 5 mins earlier). Currently, mitigating this problem by having low ttl (3 seconds) and inserting lock row every second. This way if release lock does not delete the row, it'll be deleted 3 seconds later.
