BZ #1123314 - pacemaker heat op monitor interval to 60s

https://bugzilla.redhat.com/show_bug.cgi?id=1123314

From BZ: "Rubygem-staypuft: HA: Relax the openstack-heat-engine: op
monitor interval to 60 seconds.

Now it's openstack-heat-engine: op monitor interval=30s

appears to be too resource consuming in some cases (like
openstack-heat-engine and causes false positives."
