It may be better to bind a l3 agent to an network by a CIDR instead of a uuid since when we deploy we know in advance which network address will be on which l3 agent.

I really like this idea - there is no need to limit an agent to a single
external network unless the external bridge is being used. See my
comments on the patch.
