Allow DRBD8 operation without backing storage

This patch adds the following functionality:
- DRBD8 devices can assemble without local storage (done by allowing
None in the list of children, and making DRBD8 to ignore all
children if any is None)
- DRBD8 devices can attach (i.e. identify a device) which is not
connected to backing storage but to the correct network ports; this
is a rare case in normal operation (it's what would happen if one
manually detaches the local disk, and the backing LV still exists)
