cephadm-adopt/rgw: add host target in svc_id

If multi-realms were deployed with several instances belonging to the same
realm and zone using the same port on different nodes, the service id
expected by cephadm will be the same and therefore only one service will
be deployed. We need to create a service called
`<node>.<realm>.<zone>.<port>` to be sure the service name will be unique
and well deployed on the expected node in order to preserve backward
compatibility with the rgws instances that were deployed with
ceph-ansible.
