Jan Grant 90bbd1e98f Debian element should activate eth0
Cloud images expect the primary interface to run dhclient in order
to come up and acquire an IP address. Although we have technology
to manage without this for the undercloud and so on, the seed
still relies on this machinery in order to bring up its first
interface.
