Distributed locking API should indicate whether taking lock from another node was necessary
-------------------------------------------------------------------------------------------

                 Key: JBAS-7851
                 URL: https://jira.jboss.org/jira/browse/JBAS-7851
             Project: JBoss Application Server
          Issue Type: Task
      Security Level: Public (Everyone can see)
          Components: Clustering
            Reporter: Brian Stansberry
             Fix For: JBossAS-6.0.0.M4

Callers asking for a lock should be able to distinguish these cases:

1) Lock can't be obtained
2) Lock obtained, and node already held it.
3) Lock obtained, but the node had to make a group RPC to get it

Related to this, the API should also support creation of a new lock category such that the node immediately owns the lock with no group RPC.
