Add custom playbooks for Cephadm

Adds playbooks that use the stackhpc.cephadm collection to deploy and
configure Ceph.

The cephadm-gather-keys.yml playbook gathers configuration files and
keys for a deployed Ceph cluster, and generates the necessary files for
Kolla Ansible, adding them to kayobe-config.
