[TripleO] OVB 2.0 Update

Just wanted to give everyone a heads up that there's a 2.0 development branch for OVB available. I wrote up a blog post about it http://blog.nemebean.com/content/openstack-virtual-baremetal-20-update that covers the details of what changed and where you can find it. We definitely need to make sure TripleO CI will be happy with the changes, but if anyone else is using it please also give the new branch a try and let me know how it works. -Ben
