821ff657f9 Merge pull request #27199 from derekwaynecarr/disk_eviction 
Automatic merge from submit-queue

Initial support for pod eviction based on disk

This PR adds the following:

1. node reports disk pressure condition based on configured thresholds
1. scheduler does not place pods on nodes reporting disk pressure
1. kubelet will not admit any pod when it reports disk pressure
1. kubelet ranks pods for eviction when low on disk
1. kubelet evicts greediest pod

Follow-on PRs will need to handle:

1. integrate with new image gc PR (https://github.com/kubernetes/kubernetes/pull/27199)
1. container gc policy should always run (will not be launched from eviction, tbd who does that)
  1. this means kill pod is fine for all eviction code paths since container gc will remove dead container
1. min reclaim support will just poll summary provider (derek will do follow-on)
1. need to know if imagefs is same device as rootfs from summary (derek follow-on)

Add test case to TestPodFitsResources() of scheduler algorithm

File "plugin\pkg\scheduler\algorithm\predicates", function "TestPodFitsResources()", line 199, only provide test case "one resource cpu fits but memory not", it should add test case "one resource memory fits but cpu not".

Check nil pointer in predicates.go

Should check if the pointer is nil in func filterVolumes as is done in [func predicate](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/algorithm/predicates/predicates.go#L279).

Automatic merge from submit-queue

No need to log empty string in predicates.go

If `pvcName` is empty, we don't need to log it.

c9a60e2d2c Rephrase 'pv not found in cache' warnings. 
When kubelet starts a pod that refers to non-existing PV, PVC or Node, it
should clearly show that the requested element does not exist.

Previous "PersistentVolumeClaim 'default/ceph-claim-wm' is not in cache"
looks like random kubelet hiccup, while "PersistentVolumeClaim
'default/ceph-claim-wm' not found" suggests that the object may not exist at
all and it might be an user error.

Fixes #27523
