defaults: play set_radosgw_address.yml only on rgw nodes 

This is not needed to play these tasks on nodes that are not in rgw
group.

Always playing this code makes `shrink_mon.yml` failing.

Typical error:

```
TASK [ceph-defaults : set_fact _radosgw_address to radosgw_interface - ipv4] ***
task path: /home/jenkins-build/build/workspace/ceph-ansible-prs-dev-shrink_mon/roles/ceph-defaults/tasks/set_radosgw_address.yml:21
Thursday 22 November 2018  12:34:51 +0000 (0:00:00.154)       0:00:12.371 *****
fatal: [localhost]: FAILED! => {}

MSG:

The task includes an option with an undefined variable. The error was: 'ansible.vars.hostvars.HostVarsVars object' has no attribute u'ansible_eth1'
```

Indeed, `radosgw_interface` is the network interface on rgw only. It is
expected that this same interface doesn't exist on `localhost`, so, when
running `shrink_mon.yml`, the role `ceph-defaults` is called in
`hosts: localhost` and causes the playbook to fail.
