This PR adds the support for allocatable local storage (scratch space). This feature is only for root file system which is shared by kubernetes componenets, users' containers and/or images. User could use --kube-reserved flag to reserve the storage for kube system components. If the allocatable storage for user's pods is used up, some pods will be evicted to free the storage resource.
