Expected Behavior
Using a single Lua script to verify ownership of the lock and remove it.
Current Behavior
`unlock()` method of `RedisLock` uses two separate Redis operations:
* `isAcquiredInThisProcess()`` method executes a `GET` operation to verify if the lock is owned by the process.
* `removeLockKey()`` method executes `UNLINK/DEL` operation to remove the lock.
* The `removeLockKeyInnerUnlink()`, and `removeLockKeyInnerDelete()`
methods will execute a script both verify ownership of the lock and remove it.
**Cherry-pick to `6.1.x` & `6.0.x`**
