Description of problem:
Must gather images all have a marker (or version) file; however the backup collection that happens if any of the must-gather image collections fail; doesn't meet the spec: https://github.com/openshift/enhancements/blob/master/enhancements/oc/must-gather.md#must-gather-images (mostly because its not an image).

However in order for CCX (and other teams to effectively; and programmatictilly) to distinguish between the image (or collection) we are looking to a version file as part of the backup collection (as if it were an image on its own).
