Modifying catalogue execution test to resolve component pipeline issue

Following validations were detecting changes in the image
used by CI and reporting them as issues.
While correct in case of a customer deployment,
it is unnecessary within the component pipeline.

The catalogue test will now no longer execute this validation.
    - image-serve

Following validations will recieve variable overrides.
    - check-disk-space
    - check-disk-space-pre-upgrade
    - undercloud-disk-space-pre-upgrade
    - undercloud-disk-space
