cloud-image-uploader: replicate production images beyond eastus

The image needs to be replicated to a region to be usable in that
region. It's likely we'll want to expand this list and potentially add
logic to the uploader to not replicate nightly images until they are
promoted to the latest image in the stream so I've templated it it
in the configuration.
