Description
If a replica of an object exists on a Metacat node becuase of some out of band replication (for instance, Metacat's internal replication service), a call to MN.replicate should first check for the local existence of the identifier, and if it exists, check the checksum of the object compared to the checksum in the given systemmetadata. If they match, the target node can skip the call to sourceNode.getReplica(), and can call CN.setReplicationStatus() to inform the CN that replication is complete.

- Status changed from New to Closed
The replicate() method now checks for a local copy prior to making the getReplica() call.
