Resource locks should be usable in exclusive mode and in shared mode at the same time

Current Situation

• In a situation when two orders make use of the same Resource Lock in shared mode (specifying a weight) and in exclusive mode then the Controller raises an error:
  • Invalid count=n request

Desired Behavior

• When two orders try to acquire a Resource Lock in shared mode and in exclusive mode at the same time then one of them should acquire the lock.
