[JIRA] (OVIRT-1414) Enable mirro injection process to also inject oVirt repos

Enable mirro injection process to also inject oVirt repos --------------------------------------------------------- Key: OVIRT-1414 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1414 Project: oVirt - virtualization made easy Issue Type: New Feature Components: oVirt CI Reporter: Barak Korren Assignee: Barak Korren It may be desirable to allow injecting oVirt repos in a similar way to the way other mirrors are injected. This may be useful, for example to force OST to run with the 'tested' repo configured as the fallback repo without having to add it to extra_sources.
