Make the cluster-check property configurable

Make the cluster-check property configurable

This change will make the global cluster-check property configurable
and will pick a lower default (60s) in case a pacemaker remote node
is deployed.

The cluster-recheck-interval is set to default to 15minutes by
pacemaker. This value is too high when a pacemaker remote service
is deployed. With this default value a reboot of a pacemaker remote
node will be reported as offline by pacemaker for up to 15minutes.

With this change we do the following:
1) Do nothing in case pacemaker remote is not deployed
2) When pacemaker remote is deployed and the operator has not
   specified otherwise, we set the recheck interval to 60s.
3) When the operator specifies the recheck interval we set that.
