Regional registries: Hack the manifests!

Browse Source 
Allow the gcr.io/google_containers registry to be overridden
regionally by just blasting a new KUBE_ADDON_REGISTRY out. Instead of
adding every addon to Salt and asking all of the other consumers
(Trusty, Juju, Mesos, etc) to change, just script the sed ourselves.

This is probably the 9th grossest thing I've ever done, but it works
well, and it works quickly. I kind of wish it didn't.
