Better documentation for Ceph

[willifehler]

Hey there,

could we please add better examples how to specify a list of hosts for?

pve_ceph_mon_group: "{{ pve_group }}" # Host group containing all Ceph monitor hosts
pve_ceph_mgr_group: "{{ pve_ceph_mon_group }}" # Host group containing all Ceph manager hosts
pve_ceph_mds_group: "{{ pve_group }}" # Host group containing all Ceph metadata server hosts

Let's say I only want to have 5 monitors, 5 mgrs and 5 mds but my pve group has 25 hosts.

Cheers - Willi

not to sound like a broken record, but pull requests welcome 🙂

the excerpt you've provided are just what the defaults are set to, and does not seem confusing to me so you probably have a better idea than I do on what to add to the documentation. they default to pve_group as a safeguard, but otherwise have no reason to be related to pve_group if you specify other group names.

Also this request might overlap with/be a duplicate of #68, given the title.
