With I37dcce3a67477ad3b2c36f2fd3657af18bc25c40 we removed the configuration managment of backups on the zuul server, which was happening via puppet. So the server continues in it's last state, but if we ever built a fresh server it would not have backups. Add it into the Ansible backup group, and uncomment the backup-server group to get a run and setup the Ansible-managed backups. Change-Id: I0af6b7fedc2f8f5a7f214771918138f72d298325
