7cac1dcf67 dra scheduler: fall back to SSA for PodSchedulingContext updates 
During scheduler_perf testing, roughly 10% of the PodSchedulingContext update
operations failed with a conflict error. Using SSA would avoid that, but
performance measurements showed that this causes a considerable
slowdown (primarily because of the slower encoding with JSON instead of
protobuf, but also because server-side processing is more expensive).

Therefore a normal update is tried first and SSA only gets used when there has
been a conflict. Using SSA in that case instead of giving up outright is better
because it avoids another scheduling attempt.

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.
