GEODE-5925 locks are not released in shutdown hook
If the cache is closed because the JVM is exiting we aren't releasing
locks until the DistributedSystem disconnects. This alters the behavior
of shutdown and, in particular, causes long delays in designating new
primary bucket owners and reestablishing redundancy.
This PR enables unlocking during shutdown.

> The distributed lock service is configured to avoid releasing locks while the
> cache is closing. If the cache that is closing has any primary bucket locks
> this can delay cache operations on those buckets until the cache is
> completely closed and the DistributedSystem is disconnected.
> I've seen this take over 30 seconds, causing client connections to be timed
> out on the server-side and clients failing over from one server to another
> only to be blocked by the same issue in those servers.
> Another thing I observed at the same time is that AcceptorImpl is sending
> profile updates for all partitioned regions. Those profile updates take as
> long as 2 seconds apiece to process. This also delays election of new
> primary bucket owners and it's unnecessary since
> DestroyPartitionRegion messages are later sent that remove the profiles in
> other servers.
