* used uber atomic bool instead standard in lock/unlock db

* fixing local lock optimization implementation

* fixing mysql local lock optimization implementation

* fixing cockroachdb local lock optimization implementation

* CAS wrapper to automatically restore

* added test for cas with restore

* added atomic lock to sqlite & mongo

* added atomic lock to sqlite & mongo

* fix/refactor test cas restore function

* disable lock for mongo

* mongo local lock before acquiring the db lock
