drbd: Introduce "peer_device" object between "device" and "connection"
In a setup where a device (aka volume) can replicate to multiple peers and one connection can be shared between multiple devices, we need separate objects to represent devices on peer nodes and network connections. As a first step to introduce multiple connections per device, give each drbd_device object a single drbd_peer_device object which connects it to a drbd_connection object.
