Package centric testing does not work with OSTree images

Background

The feature of package centric testing allows developers to define tests and run them before merging changes. It allows defining boards, architectures and images to test, however, it is not possible to use OSTree images. This makes sense only when used with build-custom-image as it is not possible to upgrade packages in OSTree.

Reproducibility

How often the issue is hit when repeating the test and changing nothing (same device, same image, etc.)?

Put the ✅ in the most appropriate entry:

1. ✅ always

3. rarely
