9a6f3b9388 scheduler: central ResourceClaim assume cache 
This enables connecting the event handler for ResourceClaim to the assume
cache, which addresses a theoretic race condition.

It may also be useful for implementing the autoscaler support, because now
the autoscaler can modify the content of the cache.

096e948905 dra scheduler: support structured parameters 
When a claim uses structured parameters, as indicated by the resource class
flag, the scheduler is responsible for allocating it. To do this it needs to
gather information about available node resources by watching
NodeResourceSlices and then match the in-tree claim parameters against those
resources.

c682d2b8c5 scheduler: add ResourceClass events 
When filtering fails because a ResourceClass is missing, we can treat the pod
as "unschedulable" as long as we then also register a cluster event that wakes
up the pod. This is more efficient than periodically retrying.

5269e76990 scheduler: properly skip DRA events 
Because of a misplaced `append` (should have been inside if clause, not after
it), some handler from a previous loop iteration was added again. This was
harmless because the resulting slice was only used for waiting for cache sync,
but should better get fixed anyway.

fec5233668 api: resource.k8s.io PodScheduling -> PodSchedulingContext 
The name "PodScheduling" was unusual because in contrast to most other names,
it was impossible to put an article in front of it. Now PodSchedulingContext is
used instead.

29941b8d3e api: resource.k8s.io v1alpha1 -> v1alpha2 
For Kubernetes 1.27, we intend to make some breaking API changes:
- rename PodScheduling -> PodSchedulingHints (https://github.com/kubernetes/kubernetes/issues/114283)
- extend ResourceClaimStatus (https://github.com/kubernetes/enhancements/pull/3802)

We need to switch from v1alpha1 to v1alpha2 for that.

ff741f6a96 Ensure deletion of pods in queues and cache 
When the client misses a delete event from the watcher, it will use the last state of the pod in the informer cache to produce a delete event. At that point, it's not clear if the pod was in the queues or the cache, so we should issue a deletion in both.

The pod could be assumed, so deletion of assumed pods from the cache should work.
