Skip all non-kolla based images in containers-prepare-parameter.yaml

We're introducing a filter based on container image labels for the
tripleo-modify-image role that lets us skip non-kolla based images.
The remaining images are all good potential candidates for the update.

There is no need to maintain a list of excluded images anymore or to
push to the local registry in two separate steps.
