This is a rather-messy, complex change to get the "command" package building again against the new backend API that was updated for the new configuration loader. A lot of this is mechanical rewriting to the new API, but meta_config.go and meta_backend.go in particular saw some major changes to interface with the new loader APIs and to deal with the change in order of steps in the backend API.
