Any configuration/management of things that ceph already knows about is "easy" to implement (creating pools, rbd volumes, cluster config, etc.) For spawning/configuring additional daemons, is it worth considering some kind of thin layer (another mgr module or modules?) that let the admin choose whether this is done by k8s, salt, ansible, whatever?
