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.

ec83143342 scheduler: merge Reserve and Unreserve plugins 
Previously, separate interfaces were defined for Reserve and Unreserve
plugins. However, in nearly all cases, a plugin that allocates a
resource using Reserve will likely want to register itself for Unreserve
as well in order to free the allocated resource at the end of a failed
scheduling/binding cycle. Having separate plugins for Reserve and
Unreserve also adds unnecessary config toil. To that end, this patch
aims to merge the two plugins into a single interface called a
ReservePlugin that requires implementing both the Reserve and Unreserve
methods.

42fbb1d72f Define the thresholds per the size of container images 
Given the assumption that 90% of images on dockerhub drops into this range (23~1000)MB,
this assumption is based on the container images instead of the pod.

pod might hold multiple container images, it's better to multiply the assumption by the size
of container images.

6eb0b034ac volume scheduler: move reason strings into volume code 
The scheduler doesn't really need to know in detail which reasons
rendered a node unusable for a node. All it needs from the volume
binder is a list of reasons that it then can present to the user.

This seems a bit cleaner. But the main reason for the change is that
it simplifies the checking of CSI inline volumes and perhaps later
capacity checking. Both will lead to new failure reasons, which then
can be added without changing the interface.

a57ac0725a A mapping from predicates/priorities to pluing configuration. 
This PR only implements the mapping, but does not use it. A followup PR will use this mapping to produce a framework configuration that redirects mapped predicates/priorites to be exected as plugins.

641317bdde Updated ContextData and PluginContext with Clone methods. 
This is necessary to be able to clone PluginContext during preemption.

89f936f6ac Modified the Filter interface to pass in nodeinfo instead of node name. 
This is necessary to support preemption, which relies on passing modified nodeinfo objects to the filters to simulate evicting lower-priority pods.
