6f9140e421 DRA scheduler: stop allocating before deallocation 
This fixes a test flake:

    [sig-node] DRA [Feature:DynamicResourceAllocation] multiple nodes reallocation [It] works
    /nvme/gopath/src/k8s.io/kubernetes/test/e2e/dra/dra.go:552

      [FAILED] number of deallocations
      Expected
          <int64>: 2
      to equal
          <int64>: 1
      In [It] at: /nvme/gopath/src/k8s.io/kubernetes/test/e2e/dra/dra.go:651 @ 09/05/23 14:01:54.652

This can be reproduced locally with

    stress -p 10 go test ./test/e2e -args -ginkgo.focus=DynamicResourceAllocation.*reallocation.works  -ginkgo.no-color -v=4 -ginkgo.v

Log output showed that the sequence of events leading to this was:
- claim gets allocated because of selected node
- a different node has to be used, so PostFilter sets
  claim.status.deallocationRequested
- the driver deallocates
- before the scheduler can react and select a different node,
  the driver allocates *again* for the original node
- the scheduler asks for deallocation again
- the driver deallocates again (causing the test failure)
- eventually the pod runs

The fix is to disable allocations first by removing the selected node and then
starting to deallocate.

5c7dac2d77 dra scheduler: refactor PodSchedulingContext updates 
Instead of modifying the PodSchedulingContext and then creating or updating it,
now the required changes (selected node, potential nodes) are tracked and the
actual input for an API call is created if (and only if) needed at the end.

This makes the code easier to read and change. In particular, replacing the
Update call with Patch or Apply is easy.

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.

2472291790 api: introduce separate VolumeResourceRequirements struct 
PVC and containers shared the same ResourceRequirements struct to define their
API. When resource claims were added, that struct got extended, which
accidentally also changed the PVC API. To avoid such a mistake from happening
again, PVC now uses its own VolumeResourceRequirements struct.

The `Claims` field gets removed because risk of breaking someone is low:
theoretically, YAML files which have a claims field for volumes now
get rejected when validating against the OpenAPI. Such files
have never made sense and should be fixed.

Code that uses the struct definitions needs to be updated.
