Metacat

move bulk of the Hazelcast code into HazelcastService from CNodeService so that it is centrall located - easier to manage and configure

cleaned up mock tests on hzObjectPathMap. split out code for mocking a datastore into MockObjectPathMap.

initialize Hazelcast from the custom configuration when initializing the Metacat service.

exercise the shared hazelecast system metadata map and custom loader/store by inserting normally and also directly into the map. both mechanisms allow up to read the same system metadata (only tested on single local instance)

test hzSystemMetadata Map and custom loader

copied default hazelcast configuration from the jar into hazelcast.test.properties.xml, to get instances to talk to each other.

configuring hazelcast tests

further refactoring and start of unit tests for hazelcast elements

return the test Identifier so other tests can piggyback

Update test for getReplicationStatus to reflect API change.
