Added a sleep for the podGC to catch up.

The functionality used to exist entirely in the NC which would
previously clean up pods and nodes together. Now, we simply
wait for the PodGC to see that the node is now deleted and clean up the
pods. This may take a while and hence we set a 1 minute timeout.
