Example of the contents of an archive:

I think we still need some changes:

• reference_results and reference-data seems to be confusing (which is what?). One of them needs to be renamed, maybe to results_to_compare.
• What is the tutorials_ref? It currently contains master, but in that job, I had asked for develop (see Cannot checkout tutorials develop in tests #399).
• The actual git commits of each repository are not reported anywhere. See Report git hash of each repository #401
• Do we need the metadata.yaml, docker-compose.tutorial.yaml, and docker-compose.field_compare.yaml? Are they only useful for debugging the system tests themselves? I would suggest to either delete them, or move them to a subfolder (e.g., system-tests-debug).
