[tls] Make a cert SLS IDs globally unique

At the moment most of openstack formulas have
the same ids of certs at state files, e.g.:

 nova/server.sls   - rabbitmq_ca : file_managed
 glance/server.sls - rabbitmq_ca : file_managed

So, any attempt to use the:

   salt-call state.apply

fails with:

  Detected conflicting IDs, SLS IDs need to be
  globally unique.
