Allow to deploy a newer Ceph version

We used to support N+1 server version with external Ceph, and this policy is
still adopted. For this reason we need a way to do early testing in CI.
This patch adds the ability to override the CentOS Ceph repository and
install the target cephadm release passed as input.
