* Application to storage other than local ephemeral storage.

* Application to container copy on write layers. That will be managed

by the container runtime. For a future project, we should work with

the runtimes to use quotas for their monitoring.

* Elimination of eviction as a means of enforcing ephemeral-storage

evicted by the kubelet even if their storage has been capped by
