Remove duplicate _group params.

Consolidate load balancer vips to one.

These are only use for the stats app anyway, nothing in openstack itself.
Fix a couple default param values.

- Fix default qpid_heartbeat to be in line with the rest of the services.
- Add default hex values to seeds for secret_key and admin_token.  They were
  named slightly differently in non_HA groups, so new groups were not getting
  defaults set.
- Swap glance api/registry ports.  We had them opposite the puppet defaults,
  which makes things not work with the compute node in HA.
Remove unused params for pacemaker::swift.
