DFBUGS-1702: [release-4.16] Delete the succeeded pods with duplicate tolerations to avoid alert

[malayparida2000]

PrometheusDuplicateTimestamps alert is generated due to the presence of duplicate tolerations on the osd-prepare job pods & osd-key-rotation cronjob pods. Although the root of the issue has been fixed with another fix, the existing succeeded pods need to be cleaned up to stop the alert.
Manual backport of #3056
