KPET-DB: Test origin names are confusing
At the moment, kpet-db has "suites_zip" and "kernel_tests" origins listed. These are not really clear and could be confused with each other. An alternative could be "public_tests_zip" and "private_tests_repo". We could maybe even make them both use the same representation e.g. "public/private_tests_zip" or "public/private_tests_repo". If we do any of that, we should also update the names of the variables specifying the origins. Note that any of that requires updates to the pipeline.
