Wait for container cleanup before deletion
We should wait to delete pod API objects until the pod's containers have been cleaned up. See issue: #50268 for background.
This changes the kubelet container gc, which deletes containers belonging to pods considered "deleted".
It adds two conditions under which a pod is considered "deleted", allowing containers to be deleted:
Pods where deletionTimestamp is set, and containers are not running
Pods that are evicted
This PR also changes the function PodResourcesAreReclaimed by making it return false if containers still exist.
The eviction manager will wait for containers of previous evicted pod to be deleted before evicting another pod.
The status manager will wait for containers to be deleted before removing the pod API object.
