docker-registry: provide via docker-distribution

Follow the bouncing docker-registry package. Rather than use the docker hub
registry container, we can have finer grained control if we clone and build
the docker-distribution repository directly.

Since this is distinct from the main docker package/codebase, we break the
registry back out into its own package.

We also create a baseline configuration and .service file that can be the
basis for more complex implementations.
