Switch from waiting for running pod to wait for a completed pod in image tests
Switch from waiting for running pod to wait for a completed pod in image tests

The WaitForPod* methods has changed in https://github.com/kubernetes/kubernetes/pull/109704
currently they are very strict about their expected state, so a quick
run, like in most cases in these tests where we just print usage and
complete won't likely catch running pod, so instead it's best to wait
for it to finish.
