    cluster - Improve hammer2 connect directive, add /etc/hammer2/autoconn
    
    * Improve the hammer2 connect directive, fixing a socket descriptor reuse
      race.
    
    * Monitor the file /etc/hammer2/autoconn which contains a list of hosts
      the hammer2 service demon whould automatically maintain connections to.
    
    * Adjust the dmsg_master_service() API to also allow an alternative
      signalling descriptor and callback to be specified.  This simplifies
      forced connection terminations.
    
    * Fix descriptor leak in dmsg_master_service() on closure.
