Bug 1469781

Description of problem:
This is an issue a customer is experiencing that I managed to reproduce on a couple of test VMs.
When deploying multiple RGWs on different machines, one of the RGW machine got its service enabled for itself and the RGW on the other host.

In the following setup I have a radosgw deployed on hosts ceph0 and grafana. If I list the ceph-radosgw services on ceph0, I get both:

[root@ceph0 ~]# systemctl | grep ceph-radosgw
  ceph-radosgw.service                                                           loaded active running   Ceph rados gateway
● ceph-radosgw.service                                                         loaded failed failed    Ceph rados gateway
  ceph-radosgw.target                                                                      loaded active active    ceph target allowing to start/stop all ceph-radosgw@.service instances at once

On the grafana host:
[root@grafana ceph-ansible]# systemctl | grep ceph-radosgw
  ceph-radosgw.service                                                         loaded active running   Ceph rados gateway
  ceph-radosgw.target                                                                      loaded active active    ceph target allowing to start/stop all ceph-radosgw@.service instances at once

This means that any use of ceph-rados.target will fail.
