Vulnerability ScanJob is immediately deleted

[tom1299]

What steps did you take and what happened:
Set operator.scanJobTTL: "5m" in the helm chart values in order to retain the Job and Pod for 5 minutes after completion.
Instead of retaining the Job and Pod, the scan job was immediately deleted.

What did you expect to happen:
The Scanjob and corresponding Pod to remain 5 minutes after reaching the status Completed

Anything else you would like to add:
The vulnerability controller does not honour job.Spec.TTLSecondsAfterFinished. Although the generated job manifest does contain ttlSecondsAfterFinished with the correct value, it nevertheless directly deletes completed jobs. See code here
I alter the code with the following lines before the deletion which solved the problem:

if job.Spec.TTLSecondsAfterFinished != nil && *job.Spec.TTLSecondsAfterFinished != 0 {
    log.V(1).Info("Job has TTL. Omitting deletion", "owner", owner)
    return nil
}

I can open a PR to fix this issue.
