BZ#1129896 - HA: openstack-heat-engine fails to start

https://bugzilla.redhat.com/show_bug.cgi?id=1129896

Class[quickstack::heat] needs to contain ::heat and ::heat::engine,
otherwise the ordering in Class[quickstack::pacemaker::heat] doesn't
necessarily work as one might expect.

BZ#1129896 - HA: openstack-heat-engine fails to start
Add manage_service settings to get puppet out of the way.

This is not available on all puppet modules, so adding where upstream has built
in support.  This should make starting services more consistent for these
services as pacemaker will have full control of starting and stopping the
services without the chance of puppet having already done so, which potentially
could cause confusion for pacemaker.
