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.

_`kube_tag`
This label allows users to select `a specific Kubernetes release,
based on its container tag

If unset, the current Magnum version's default Kubernetes release is
installed.
_`kube_dashboard_enabled`
This label triggers the deployment of the kubernetes dashboard.
The default value is 1, meaning it will be enabled.
