Add support for test packages on MR
Testing is a key value in Apertis, this commit adds support for testing packages build in the context of a Merge Request. With this new feature packages can add metadata to debian/apertis to instruct the pipeline to trigger the build of a new image with the new version packages and test them in LAVA.
Additionally is possible to filter the tests to run to avoid wasting resources.
