A contrib directory would not be considered packagable, but we have an increasing need to package overcloud_containers.yaml and tripleo_kolla_template_overrides.j2 for image building and pulling in CI and other environments. This change renames contrib to container-images and adds symlinks in contrib so that scripts[1] and documentation[2] that depend on this location can be moved over to using packaged container-images rather than git contrib.
