Story (Required)

As a QE, I don't want to manually update Hive image sets to latest OpenShift versions.

Background (Required)

We already have a task, pipeline and a cronjob that is supposed to update the image sets but it doesn't work correctly.

1. it uses a static PVC, should use volume claim template instead
2. it's not able to remove the content of PVC when cloning the plumbing repository
3. it cannot clone plumbing repository, probably using a wrong ssh key
4. cron job runs with "@weekly" schedule, it is not clear when it would run, make it explicit
5. git diff is causing warnings "Not a git repository"
6. git push/pipeline fails when there is nothing to push which is OK state

Acceptance Criteria (Mandatory)

1. All issues listed above are solved
