[JIRA] (OVIRT-1868) Allow engineers to write Jenkinsfiles

Allow engineers to write Jenkinsfiles ------------------------------------- Key: OVIRT-1868 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1868 Project: oVirt - virtualization made easy Issue Type: New Feature Components: Standard CI (Pipelines) Reporter: Roman Mohr Assignee: infra Looks like standard-ci switched internally to use Jenkinsfiles. However it would be very valuable for engineers, if they could just write their Jenkinsfile, instead of all the usual standard-ci yamls/scripts. With the Jenkinsfile the chroot based approach seems to be pretty obsolete, if you allow people to use the docker agent for the Jenkinsfile. For KubeVirt it would make standard-ci finally really valuable.
