As described in bug #1728527 cibadmin does not expose the state of
the pacemaker-remote nodes which means hostmonitor cannot track
them. This change switches to use crm_mon to check the status of
remote nodes if the new config option host.restrict_to_remotes
to set to True. This will trigger host monitor to use crm_mon
to monitor nodes and will only monitor nodes that are marked
as remotes (not members).
