Fix k8s_drain runs into timeout with pods from stateful sets. (#793)

Browse Source 
SUMMARY
Fixes #792 .
The function wait_for_pod_deletion in k8s_drain never checks on which node a pod is actually running:
            try:
                response = self._api_instance.read_namespaced_pod(
                    namespace=pod[0], name=pod[1]
                )
                if not response:
                    pod = None
                time.sleep(wait_sleep)
This means that if a pod is successfully evicted and restarted with the same name on a new node, k8s_drain does not notice and thinks that the original pod is still running. This is the case for pods which are part of a stateful set.
