In order to be able to unit test the tunnel flow setup code we
need to be able to generate netdevs that appear to be like
tunnel devices. This adds a dummy_tunnel netdev with two
differences from the normal dummy devices: the ability to set and
read config and a different type to identify them as needing
tunnel translation.
