Deprecate Ceph deployment

Browse Source 
There are now several good tools for deploying Ceph, including Ceph
Ansible and ceph-deploy. Maintaining our own Ceph deployment is a
significant maintenance burden, and we should focus on our core mission
to deploy OpenStack. Given that this is a significant part of kolla
ansible currently we will need a long deprecation period and a migration
path to another tool.

debug:
msg: >-
Support for deploying Ceph via Kolla Ansible is deprecated. In a future
release support for deploying Ceph will be removed from Kolla Ansible. Prior
to this we will ensure a migration path to another tool such as Ceph
Ansible (http://docs.ceph.com/ceph-ansible/master/>) is available. For new
deployments it is recommended to use another tool to deploy Ceph to avoid a
future migration. This can be integrated with OpenStack by following the
external Ceph guide
(https://docs.openstack.org/kolla-ansible/latest/reference/storage/external-ceph-guide.html).
