command: Various updates for the new backend package API 

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.
