[Pacemaker] Update pygui to support pacemaker

[Xinwei Hu]

Hi all,

  We are about to update mgmtd to support pacemaker, here are some
issues we want to clarify.

1. mgmtd used to get a list of all nodes from hb. This is about to be
changed. But should we get it from crm ? Or from ais ? The later one's
better at first glance.

2. mgmtd use to get a list of hb parameters:
      apiauth, auto_failback, baud, debug, debugfile, deadping,
deadtime, hbversion, hopfudge,
      initdead, keepalive, logfacility, logfile, msgfmt,
nice_failback, node, normalpoll,
      stonith, udpport, warntime, watchdog, cluster
   I suppose all of these are not exist in pacemaker anymore. Will be
safe to remove them all ?

3. Type of node. For hb, there are normal node and ping node. What
about pacemaker ?

  Thanks.
