Description of problem:
     In the "ceph-iscsi-ansible.yml" we need a check for rsync in the seed_mon.
The admin keyring is copied from the seed_mon to the gateway nodes.
Currently we are seeing a failure like this:

TASK: [ceph-iscsi-gw | sync the admin keyring from the seed monitor to each gateway node] ***
failed: [nighthawk -> harvard] => {"cmd": "rsync --delay-updates -F --compress --archive --rsh 'ssh  -S none -o StrictHostKeyChecking=no' '--out-format=<<CHANGED>>%i %n%L' /etc/ceph/ceph.client.admin.keyring ''", "failed": true, "rc": 2}
msg: [Errno 2] No such file or directory
