9b74e24fa3 Merge pull request #28769 from wojtek-t/optimize_priorities 
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.

Automatic merge from submit-queue

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).

a405df4391 Merge pull request #25710 from xiangpengzhao/fix_predicate 
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

41ed85479a move predicates into library (address #12744) 
DONE:
1. refactor all predicates: predicates return fitOrNot(bool) and error(Error) in which the latter is of type
	PredicateFailureError or InsufficientResourceError. (For violation of either MaxEBSVolumeCount or
        MaxGCEPDVolumeCount, returns one same error type as ErrMaxVolumeCountExceeded)
2. GeneralPredicates() is a predicate function, which includes serveral other predicate functions (PodFitsResource,
        PodFitsHost, PodFitsHostPort). It is registered as one of the predicates in DefaultAlgorithmProvider, and
        is also called in canAdmitPod() in Kubelet and should be called by other components (like rescheduler, etc)
        if necessary. See discussion in issue #12744
3. remove podNumber check from GeneralPredicates
4. HostName is now verified in Kubelet's canAdminPod(). add TestHostNameConflicts in kubelet_test.go
5. add getNodeAnyWay() method in Kubelet to get node information in standaloneMode

TODO:
1. determine which predicates should be included in GeneralPredicates()
2. separate GeneralPredicates() into:
	a. GeneralPredicatesEvictPod() and
	b. GeneralPredicatesNotEvictPod()
3. DaemonSet should use GeneralPredicates()
