bonding: kernel bonding device creation

Creates virtual kernel devices as needed. Since the manager is
initialized after the connections have been loaded no
CONNECTIONS_ADDED notification is received for connections parsed
at startup.

Therefore walks the loaded connections looking for bonding
connections.

Connections added on the fly are handled via the notifications.

Connection renaming and deleting is not supported yet.
