Merge pull request #44674 from madhusudancs/fed-dump-logs-pod-pods

Automatic merge from submit-queue (batch tested with PRs 44499, 44674)

Strip "pods/" prefix from the pod names returned by kubectl get pods.

Note that the result returned by kubectl get -o name has plural prefixes "pods". We were already trying to remove the prefix "pod", but that's not how the results are returned unfortunately.

**Release note**:
```release-note
NONE
```
