* ACL rules using the new operation VIRTUALHOSTNODE apply to VHN model objects.
* ACL rules using the operation VIRTUALHOST apply to VH model objects for CREATE, UPDATE and DELETE.  This
  is a change from previous version where BROKER operation permission was required.
* For HA, VIRTUALHOSTNODE permission is required to perform updates on RemoteReplicationNodes.
