ceph: manage /etc/ceph/ceph.conf on osd and mon/mgr/mds hosts
Bring the hand-maintained /etc/ceph/ceph.conf under Puppet on the
prodnxsr ceph cluster (fsid de96a98f). The file is identified per host
by role: k8s roles include profiles::ceph::osd only and get a [global]
section; the incus node role also includes profiles::ceph::mds and
additionally gets the [mds] + [mds.*] sections.

- Add cluster topology as a single source of truth in common.yaml:
  cluster_public_ips (all 13 ceph host /32s), mon_initial_members, and
  the mds_instances map (two mds daemons per mon/mgr/mds host).
- Render /etc/ceph/ceph.conf from that topology in the reworked
  client.conf.erb, preserving the live two-space indent and key order.
- Gate the [mds] sections on render_mds_config, set true only in the
  incus node role hiera (the role that includes profiles::ceph::mds).
- Drop the hard Package[ceph-common] dependency when the class does not
  manage the package (cephadm/profiles::packages deliver it on the k8s
  and incus hosts).
- Enable manage_ceph_conf on the k8s and incus node roles.

public_network is normalized to all 13 ceph host /32s on every host;
this rewrites it on the mon/mgr/mds hosts (adding .1-.8) as the one
intended content change. RGW hosts keep their profiles::ceph::conf
variant and are untouched.
