Steve Baker a8139d648d overcloud_containers.yaml.j2 map images to services
This change adds a services key to each entry in
overcloud_containers.yaml.j2 which contains a list of
tripleo-heat-templates docker resource types which consume this image.

The intent is for the prepare command to use this plus the heat
environments to produce an image list that only contains images for
services actually being deployed. This targeted list will make image
upload operations quicker, which is one issue affecting containers in
CI.
