Metacat

Add the listener for LifecycleEvent state changes

synchronizeLocalStore() when the cluster has a LifecycleEvent state change to RESUMED.

refactor memberAdded code to separate method - synchronizeLocalStore for possible reuse

-use MembershipListener to keep new members' backing store for system metadata synchronized with the shared system metadata map.
-remove the unused InstanceListener interface

Add a few more debugging statements to HazelcastService for troubleshooting hazelcast map concurrency.

add an alternative method for loading system metadata identifiers but leave it commented out. We may find that using the ObjectList method is too much overhead, but it will always be consistent with what metacat reports for listObjects().

add note about long-running load for shared system metadata map

refactor IdentityManager.createSystemMetadata(sm) to be insertSystemMetadata(sm) so that it is clear that this method inserts the SM object into the backing store. This differentiates it from the "generation" methods we use when we need to create SM about pre-existing objects or objects we get from non-D1 api calls.

additional logging of the config file being used - seem to have thread locking on the xmlConfig use when running under ant/junit

In IdentifierManager.updateSystemMetadata(), add a check for invalid system metadata (fields that throw a NullPointerException on access) to ensure that system metadata is populated correctly. Updated calling classes to handle the exception.
