Whether to wait already locked node to be unlocked.

If `Waitable' is set to true Lock method will create waitable lock, that will be taken once other transactions that hold lock to that node are committed / aborted.

Note

Lock method DOES NOT wait until lock is actually acquired. Waiting should be done using corresponding methods of ILock.
