[JIRA] (OVIRT-907) Add CI for mock_runner.sh

Add CI for mock_runner.sh ------------------------- Key: OVIRT-907 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-907 Project: oVirt - virtualization made easy Issue Type: Improvement Components: Jenkins Reporter: Barak Korren Assignee: infra We have some CI jobs running on our "Jenkins" repo right now. Those jobs mostly check YAML, but they are also useful for checking changes to mock_runner.sh because they are running inside it. However: # These jobs do a full YAML check even when it is not needed. # We're not actually checking mock_runner.sh for all the platforms it simulates. We've already seem some regressions happen in the CI system because we don't have enough tests for mock_runner.sh This ticket is for creating good CI coverage for mock_runner.sh, all that is needed to be done in practice is make some changes to the check_patch.sh script and the YAML so that: * YAML checking is skipped if no JJB-related changes were done * Various features of mock_runner like the installation of packages for the *.packages files are checked. * The tests are ran for all platforms that mock_runner.sh supports.
