Increase the version number after updating the existing object's system metadata in the update method.

Fixed a possible null exception in the updateSystemmetadata method.

In the MN.updateSystemMetadata method, when we set the obsoletedBy and obsoletes method, we will check if those values already exist in other chains.

Add the identifier in the message of the exception when a client tries to reset the obsoletes or obsoletedBy fields.

Check the obosoletedBy and Obsoletes only can be set once.

The method of setReplicationstatus can be called by CNs and MNs.

merge from V2 impl: check for optional "failure" param instead of throwing exception when it is missing (often is). https://redmine.dataone.org/issues/7283

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()
