Clayton Coleman de9cdab5ae kubelet: Prevent runtime-only pods from going into terminated phase ...

If a pod is already in terminated and the housekeeping loop sees an
out of date cache entry for a running container, the pod worker
should ignore that running pod termination request. Once the worker
completes, a subsequent housekeeping invocation will then invoke
terminating because the worker is no longer processing any pod
with that UID.

This does leave the possibility of syncTerminatedPod being blocked
if a container in the pod is started after killPod successfully
completes but before syncTerminatedPod can exit successfully,
perhaps because the terminated flow (detach volumes) is blocked on
that running container. A future change will address that issue.
