Automatic merge from submit-queue

Change storeToNodeConditionLister to return []*api.Node instead of api.NodeList for performance



Currently copies that are made while copying/creating api.NodeList are significant part of scheduler profile, and a bunch of them are made in places, that are not-parallelizable.

Automatic merge from submit-queue

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".

Automatic merge from submit-queue

Optimize priorities in scheduler

Ref #28590

It's probably easier to review it commit by commit, since those changes are kind of independent from each other.

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
