action #38807

Updated by SLindoMansilla about 3 years ago

## Motivation
We use the medium "iso/SLE-12-SP4-Server-DVD-x86_64-Build????-Media2.iso" while using it as repo.
We thought we used that ISO to extract the repository, but the ISO and the repository are synced and handle into OSD in different tasks, so we don't need to sync nor have a job setting with those unused isos.

However we need to account for the medium (so it will get deleted by openqa-gru.service), see #38804 for fix to medium2.
There are still some other ISOs for modules that need to be checked.

## Acceptance criteria
* **AC1:** All synced assets are accounted for in test asset variables but unused assets are not provided as assets on jobs that users want to clone

## Further details

#### s390x

Our current s390x jobs reference an ISO as well but we never use the ISO directly but only repos from that. These jobs should also be handled
