[JIRA] (OVIRT-1124) Automate oVirt official release process

Automate oVirt official release process --------------------------------------- Key: OVIRT-1124 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1124 Project: oVirt - virtualization made easy Issue Type: New Feature Reporter: eyal edri Assignee: Barak Korren Current release flow is 100% manual and depends on multiple sources of built RPMs. We should support one automated flow which will use the standard CI to build and publish official oVirt releases. Some initial thoughts to consider: * We'll need to trigger 'build-artifacts' job when a new tag is added to project and build the official release ( in ovirt-engine we do it already with a special if in build-artifacts.sh ) * The new RPMS should pass OST / Experimental verification and deployed to 'pre' repo after verification. * We should support only this flow and not external build systems like koji/copr, any project maintainer that still wants to build in other system is welcome, but for oVirt repos we'll do it from the official tag * Consider using repoman for signing the RPMs when we compose the 'pre' repo * If a project doesn't have a new tag to build from, we'll use the latest official release of that project.
