    pmmgr: add general monitor-program launching option
    
    Extend pmmgr with the ability to start arbitrary pcp-flavoured
    monitoring programs for PMCDs it finds.  This may be used to
    automatically launch pcp2graphite, pmrep, or other monitoring tools,
    as long as they understand the "-h HOSTSPEC" option.  QA & docs
    included.
