This service provides support for taking read/write locks.
It is intended for use with fabric, but it is still a general service. The locks are in a separate namespace from other locks in the server, and there is also no interactions with transactions (i.e. locks are not released on commit/abort).
These locks are implemented using the metadata lock (MDL) subsystem and thus deadlocks involving locking service locks and other types of metadata will be detected using the MDL deadlock detector.
