Review comment:
@marcaurele : Do we just need to add the debug logger if lock is not
acquired ?
Please confirm.

> *ISSUE :*
> createSnapshotPolicy API create multiple entries in DB for same parameters,
> if multiple threads are executed in parallel.
> *STEPS TO REPRODUCE :*
> # Created a new machine having root and data disk.
> # Make sure that no existing snapshot policy is present for the volume.
> # Execute multiple threads in parallel for createSnapshotPolicy API having
> all required parameters exactly same.
> # Verify table snapshot_policy in DB, will get multiple entries for same
> policy.
> # Once again execute same multiple threads, by changing any API parameter,
> will see that existing entries are getting modified in DB and no new entries
> are added.
