For alpha, there is one apiserver feature gate and two client-go feature gates controlling
CBOR. They were initially wired to separate test-only feature gate instances in order to prevent
them from being configurable at runtime via command-line flags or environment variables (for
client-go feature gates outside of Kubernetes components). All of the integration tests required by
the KEP as alpha criteria have been implemented. This adds the feature gates to the usual feature
gate instances and removes the temporary code to support separate test-only feature gate instances.

The new DRAAdminAccess feature gate has the following effects:
- If disabled in the apiserver, the spec.devices.requests[*].adminAccess
field gets cleared. Same in the status. In both cases the scenario
that it was already set and a claim or claim template get updated
is special: in those cases, the field is not cleared.
Also, allocating a claim with admin access is allowed regardless of the
feature gate and the field is not cleared. In practice, the scheduler
will not do that.
- If disabled in the resource claim controller, creating ResourceClaims
with the field set gets rejected. This prevents running workloads
which depend on admin access.
- If disabled in the scheduler, claims with admin access don't get
allocated. The effect is the same.
The alternative would have been to ignore the fields in claim controller and
scheduler. This is bad because a monitoring workload then runs, blocking
resources that probably were meant for production workloads.
Added tests, info about new feature gate in error message, fixes from review
Added basic e2e test
Added unit tests
Ran hack/update-featuregates.sh
Tolerate updates to existing resources after disabling feature gate
Added feature gate to versioned_kube_features.go
Fixed existing tests
Use PodValidationOptions for validation instead of using feature gate directly
Relaxed validation for allowing zero in prestop hook sleep action
* Promote TopologyManagerPolicyOptions feature to GA
* Promote PreferClosestNUMANodes TopologyManagerPolicyOption to stable

This removes the DRAControlPlaneController feature gate, the fields controlled
by it (claim.spec.controller, claim.status.deallocationRequested,
claim.status.allocation.controller, class.spec.suitableNodes), the
PodSchedulingContext type, and all code related to the feature.
The feature gets removed because there is no path towards beta and GA and DRA
with "structured parameters" should be able to replace it.
