Change the registered name for a node in a directory service.

     RENAME [DECNET] NODE old-node-name NEW_NAME new-node-name
         [ DIRECTORY_SERVICE dir-service ]
         [ SYNONYM new-synonym-name ]
         [ REVERSE_DIRECTORY rev-dir-name ]
         [ SYNONYM_DIRECTORY syn-dir-name ]

 This is used when a node's name has been changed, and that change needs
 to be reflected in a directory service.  The attribute values stored
 under the name remain unchanged.

 Nodes can be renamed only within a directory service.  They cannot be
 renamed from one type of directory service to another.

 This function only changes the name in the directory service, and does not
 directly affect the name on the node itself.  To change the name on the
 node, use the node's network configuration utility.
