[pve-devel] [PATCH manager v2] fix #1430: ceph init: allow to specify separate cluster network

Allow to specify a separate cluster network when initializing ceph.
Ceph docs[0] imply a possibility for performance increase and
enhanced security in environments where the public network serves not
fully trusted peers, which could else provoke a DOS to the cluster
traffic[0].

Make this optional, but if passed `network` is required too.

changes v1 -> v2:
* use a more expressive and user friendlier description for the new property as
  suggested by Tim
