create clean segregation of storage networks

Both swift and ceph now require two storage segments not one.
For Ceph you have a "public" network, this is the network by which librados will reach OSD (monitors use this network as well) and replication network which is used for OSDs to talk to each other.
Latest Swift has introduced this concept as well. with the Storage network proxy to object servers and a replication network used by all background anti-entropy processes.

We are currently mapping one of these network segments in ceph to management network, which is not necessarily the right thing to do as storage/public ceph networks are high bandwidth network segments. We need to be able to cleanly segregate these various storage networks away from the management network.
