Document use of kube_tag label

Explain how to select a specific Kubernetes version by specifying the
kube_tag label.

In the process, also fix the broken list of images that must be
mirrored, immediately above kube_tag.

In addition, fix an unrelated whitespace error in
specs/containers-service.rst which would cause tox -e docs to fail.
