Code review comment for lp:~vishvananda/nova/lp710959

I don't think it is reasonable to try and get this into Bexar. There is already a note in release notes saying the current limitations of flatdhcp. I might be able to mock out and write tests for parts of this, but the only way i actually feel comfortable that it is working is to run smoketests against a multinode deploy of it. There is too much that just happens to work on one machine that breaks against more than one. On the upside, I've successfully deployed this onto multiple vms with vagrant and it actually works! Patches for smoketests are coming soon, as well as instructions for doing a full multinode deploy and test.
