Merge pull request #101467 from ingvagabund/noderesources-replace-IsScalerResourceName-with-nodeinfo-allocatable-scalar-resource-presence 
noderesource: node info already knows which resources are scalar

7286f9712a pkg/scheduler: drop Resource.ResourceList() method 
The method is used only for testing purposes. Given Resource data type
exposes all its fields, any invoker of ResourceList that is still
using the method outside of kubernetes/kubernetes can still either
copy paste the original implementation or implement a custom method
that's converting resources into proper Quantity data type.

Given the hugepage resource is a scalar resource, it's sufficient
the underlying code under fit_test.go to take into account any
extended resources. For predicate_test.go, the hugepage
resource does not play any role as the General predicates test cases
does not set any scaler resource at all.

Additionally, by removing ResourceList method, pkg/scheduler/framework
can get rid of dependency on k8s.io/kubernetes/pkg/apis/core/v1/helper.

11d6576f83 noderesource: node info already knows which resources are scalar 
NodeInfo.Allocatable.ScalarResources already knows which resources
are scaler. Also, if the resource name is not present,
it's pointless to compute score for a resources the node can not allocate
since nodeInfo.Allocatable.ScalarResources[resource] is zero for the case.
And both leastRequestedScore and mostRequestedScore returns 0 score
for nodes with zero allocatable resource.
The balancedResourceScorer deals only with CPU and memory which
are not scalable resources.

578ff3ec34 Move Taint/Toleration helpers to component-helpers repo 
This is part of the goal for scheduling to remove dependencies on internal
packages for the scheduling framework. It also provides these functions in an
external location for other components and projects to import.

ba72411aa2 Move GetPersistentVolumeClaimClass to component-helpers 
The goal of this move is related to issue 89930, to break the dependence
of scheduling plugins on internal helpers. This function can easily move to
component-helpers where it will be used by other components as well.

Dave Chen
7315c1f6dd Show the details on the failure of preemption 
Since the filter status is missed for the phase of preemption, there
will be no way to tell why the preemption failed for some reasons, and
those reasons could be different with the status from the main scheduling
process (the first failed plugin will hide other failures in the chain).

This change provides verbose information based on the node status generated
during pod preemption, those information helps us to diagnose the issue which
is happened during pod preemption.

ccd8eb3b1b Only process all nodes when incoming pod has no preferred affinity 
Currently, in interpodaffinty plugin, it only processes all nodes when the incoming
pod with affinity. Actually, it only cares about all nodes when the incoming pod
with preferred affinity. Then it will reduces the number of nodes need to be
processed.

a8873e1a43 Track pods with required anti-affinity 
This is a performance optimization that reduces the overhead of inter-pod affinity PreFilter calculaitons. Basically
eliminates that overhead when no pods in the cluster use required pod anti-affinity. This offered 20% improvement on 5k clusters for preferred anti-affinity benchmarks.

012245c5b9 Add LabelSelector validation in Pod Affinity/AntiAffinity Filter and Score plugins 
The lack of this validation on incoming pods causes unpredictable cluster outcomes
when later calculating affinity results against existing pods (see #92714). This fix
quickly addresses the main source where these problems should be caught.

It is unfortunately difficult to add this validation directly to the API server due
to the fact that it may break migrations with existing pods that fail this check. This
is a compromise to address the current issue.

ff3e5e06a7 GenericEphemeralVolume: initial implementation 
The implementation consists of
- identifying all places where VolumeSource.PersistentVolumeClaim has
  a special meaning and then ensuring that the same code path is taken
  for an ephemeral volume, with the ownership check
- adding a controller that produces the PVCs for each embedded
  VolumeSource.EphemeralVolume
- relaxing the PVC protection controller such that it removes
  the finalizer already before the pod is deleted (only
  if the GenericEphemeralVolume feature is enabled): this is
  needed to break a cycle where foreground deletion of the pod
  blocks on removing the PVC, which waits for deletion of the pod

The controller was derived from the endpointslices controller.

028af0970f Cut off the cost to run filter plugins when no victim pods are found 
If no potential victims could be found, there is no need to evaluate the node
again, since its state didn't change.

It's safe to return and thus prevent scheduling from running the filter plugins
again.

NOTE:
A node that is filtered out by filter plugins could pass the filter plugins if
there is a change on that node, i.e. pods termination on that node.

Previously, this could be either caught by the normal `schedule` or `preempt` (pods
are terminated when the preemption logic tries to find the nodes and re-evaluate
the filter plugins.)

Actually, this shouldn't be taken care by the preemption, consider the routine
of `schedule` is always running when the interval is "zero", let `schedule`
take care of it will release `preempt` from something irrelevant with the `preemption`.

Due to above reason, couple of testcase as well as the logic of checking the existence
of victim pods are removed as it will never happen after the change.

0efbbe8555 CSIStorageCapacity: check for sufficient storage in volume binder 
This uses the information provided by a CSI driver deployment for
checking whether a node has access to enough storage to create the
currently unbound volumes, if the CSI driver opts into that checking
with CSIDriver.Spec.VolumeCapacity != false.

This resolves a TODO from commit 95b530366a.

3e65fe4378 Change the exception to avoid the cost of preemption 
node's labels doesn't contain the required topologyKeys in `Constraints`
cannot be resolved by preempting the pods on that pods.

One use case that could easily reproduce the issue is,
- set `alwaysCheckAllPredicates` to true.
- one node contains all the required topologyKeys but is failed in predicates
  such as 'taint'.
- another node doesn't hold all the required topologyKeys, and thus return `Unschedulable`
  status code.
- scheduler will try to preempt the pods on the above node with lower priorities.
