Update pacemaker service management calls.

RHEL 7 uses systemd, so switch our calls to use the new wrapper in
puppet-pacemaker, pacemaker::resource::service (wrapped in
quickstack::pacemaker::resource::service, since we need to only run commands
on one node - that support is not yet baked into the pacemaker module).
Pass in setup_cluster flag to corosync.

Since the pacemaker in RHEL 7 has some additional setup with must be done only
on one node, pass in a flag to tell puppet-pacemaker if it shoudl run those
additional steps on a given node.
Fix file name for storage_backend::cinder.

We renamed the class and the hostgroup, but missed the file rename.
