This is useful in case that the pod owns some resources, because then
waiting for the pod ensures that those resources also were removed.
This should not matter at the moment because pods typically are not
owners of any other object, but that will change with the introduction
of generic ephemeral inline
volumes (https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1698-generic-ephemeral-volumes).
Moving pod related functions from e2e/framework/pv_util.go to
e2e/framework/pod in order to allow refactoring of pv_util.go into its
own package.
