Fixed a possible null pointer exception bug. https://redmine.dataone.org/issues/7280

Only CNs can call those methods:
CNCore.registerSystemMetadata()
CNCore,updateSystemMetadata()
CNReplication.setReplicationStatus()
CNReplication.updateReplicationMetadata()
CNReplication.deleteReplicationMetadata()

On mn.update and mn.updateSystemMetadata, those clients are allowed:
1. CNs.
2. Clients with appropriate permission calling the method on the authoritative nodes.

When compare the dateUploaded, now we use sysmetadata.getDateUploaded().getTime(). It used systemmetadata.getDateUploaded() (Date objects) to compare.

Add code to catch the BaseException in the updateSystemMetadata method.

Add the code to handle if the cn is null.

Handle multiple versions (v1 and v2) of a service in getCapacity method.

Use the NodeReference object to replace the replicaStatus to restrict the listObjects method.

[re]register DOI when system metadata is updated (typically access policy). https://projects.ecoinformatics.org/ecoinfo/issues/6796

Change the signature of listObject method - remove replicaStatus and add nodeId.
