Fixup network configuration for ext-net
We currently make the external network a single-node gre network but
this is not at all correct for HA environments - we need a provider
network, which means having a bridge mapping, a flat network
specified, and then because we run the same ovs config everywhere we
need br-ex on the hypervisors too. This is entirely reasonable since
DVR will require this as well (and solve lots of scaling issues...).
