Metacat

only "save" to the shared system metadata map - not directly to the table store.

rely on Hazelcast to store the SystemMetadata locally for the node. Entry event listeners store the shared system metadata on their local node when alerted. TODO: remove old replication code that included system metadata xml when replicating scimeta and data

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

verify that the sysmeta checksum value matches the computed checksum value when calling create()
https://redmine.dataone.org/issues/1795

check for null pointers when adding system metadata/creating records during cn.create()

removing unneeded class (never used)

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.

handle entryAdded and entryUpdated the same - update the entry if it exists, otherwise create it

handle entryAdded (to hzSystemMetadata) to store sysmeta to local store when it is not already present
