Ceph init should include possibility to add replication network

We need the ability to create ceph with different public and replication networks. I miss an option to define --cluster-network <string>.

I would create a variable to define cluster-network and if this cluster network is defined, this option should be added.

Something like that:

  command: 'pveceph init --network {{ pve_ceph_network }} --cluster-network {{ pve_ceph_cluster_network }}'

If you could, can you split off the replication network changes into a single PR (those changes look fine to me), and then we can look further at the OSD creation steps? Since it’s off-topic/better for that discussion to happen in a separate issue, I moved those comments to #73.

Creating another task checking the osd’s is what I had in mind. I’ll include the changes in my feature branch, should be available within a few days.
