         *          *  Performs a watch for the serving status of the requested service.
         *  The server will immediately send back a message indicating the current
         *  serving status.  It will then subsequently send a new message whenever
         *  the service's serving status changes.
         * 
         *  If the requested service is unknown when the call is received, the
         *  server will send a message setting the serving status to
         *  SERVICE_UNKNOWN but will *not* terminate the call.  If at some
         *  future point, the serving status of the service becomes known, the
         *  server will send a new message with the service's serving status.
         * 
         *  If the call terminates with status UNIMPLEMENTED, then clients
         *  should assume this method is not supported and should not retry the
         *  call.  If the call terminates with any other status (including OK),
         *  clients should retry the call with appropriate exponential backoff.
