External load balancer deployment fails with: Error: Could not find dependency Pacemaker::Resource::Ocf[openstack-core] for Pacemaker::Constraint::Base[openstack-core-then-httpd-constraint]
The Overcloud uses a fake openstack-core resource to replace keystone (now accessed through httpd). However, the Overcloud did not create openstack-core when using an external load balancer. This caused puppet to fail when creating Pacemaker constraints that required openstack-core. This fix ensures creation of the openstack-core resource for any deployment configuration. The deployment succeeds and creates the needed constraints.
Giulio - I'm assigning this back to you (I'm guessing it got moved when the component was changed). It looks very close to landing, so can you just make sure it passes CI and gets the +A necessary?
