[kolla] Repository setup in non-internet environment.

Hi, I'm thinking about the deployment in non-internet environment. As we know Kolla has already prepared docker registry and kolla-build to let user can create local registry for deployment. But there's still have two problem about non-internet deployment. 1. Docker-ce repository. 2. Pip repository. (Also having others perhaps.) Does Kolla planning to support non-internet deployment? I would like to do this if possible. Looking forward to hearing from you, Eddie.
