Currently, the d_concurrency.h/.cpp set of utilities are under the lock_manager library, but they reach into TransactionResources in order to obtain the locker interface. On the other hand, TransactionResources is under the shard_role_api library that is higher on the architectural stack than the lock_manager.

Because of this, we have a dependency order inversion.

This ticket moves the rest of the d_concurrency.h/.cpp utilities into the shard_role_api_stor_ex library, where they are more appropriate to be located and cleans up the lock_manager library.

Note that, we can't yet remove the cyclic dependency, but this is just a step in that direction.
