Description

Currently, org.dataone.cn.service.replication.v1.ReplicationService implements the CNReplication API to field REST calls from both MNs and CNs, and also the Hazelcast EntryListener and ItemListener interfaces to monitor changes to 1) the hzSystemMetadataMap and 2) the hzReplicationTasks queue.
This class should be refactored into 1) a ReplicationManager class that implements the Hazelcast interfaces and creates and submits ReplicationTasks, and 2) a ReplicationService (implemented in edu.ucsb.nceas.metacat.dataone.CNodeService) that handles the REST calls.
