Title: fix(controller): remove /run/deis/determine_registry

This script is backwards-incompatible with existing clusters. Moving the
calls to etcd directly into the unit file removes the dependency and
ultimately makes master backwards-compatible again.

We don't necessarily need to check if the values are present or not. If they're not there, the pull will fail due to the image name being `:/`.
