    Control channel for queue daemons to request graceful shutdown, restart, or update to listen to a newly added or reconfigured site.
    
      queuectl.php --update -s<site>
      queuectl.php --stop
      queuectl.php --restart
    
    Default control channel is /topic/statusnet-control. For external utilities to send a site update ping direct to the queue server, connect via Stomp and send a message formatted thus:
    
      update:<nickname>
    
    (Nickname here, *not* server hostname! The rest of the queues will be updated to use nicknames later.)
    
    Note that all currently-connected queue daemons will get these notifications, including both queuedaemon.php and xmppdaemon.php. (XMPP will ignore site update requests for sites that it's not handling.)
    
    Limitations:
    * only implemented for stomp queue manager so far
    * --update may not yet handle a changed server name properly
    * --restart won't reload PHP code files that were already loaded at startup. Still need to stop and restart the daemons from 'outside' when updating code base.
