Managing save artifacts MRs is a bit tricky and causes population of MRs being merged in the pipeline repo. There is new fromager feature that allows us to use URLs for such files instead of a path on the local system

Goal: 

• Instead of passing a path to the build order file lets use a URL so that we don't have to store these files in the pipeline repo itself

Acceptance Criteria:

• Store the build order files as artifacts within the gitlab package registry
• Use the URL to these artifacts to consume the build order file and graph file
