----------------------------------------

If JBCLUSTER-223 is done before this work is done, please move this JIRA to the JBCLUSTER project, as that's where the code will be.

> 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
> Purpose of this is to use condition 3) as a way to detect failover.
> 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.
