The v1alpha3 version is still needed for DeviceTaintRule, but the rest of the
types and most structs became obsolete in v1.32 when we introduced v1beta1 and
bumped the storage version to v1beta1.
Removing them now simplifies adding new features because new fields don't need
to be added to these obsolete types. This could have been done already in 1.33,
but wasn't to minimize disrupting on-going work.

For compatibility reasons, the old functions without the ctx parameter still
get generated, now with context.Background instead of context.TODO. In practice
that code won't be used by the client-go reflector code because it prefers
the *WithContext functions, but it cannot be ruled out that some other code
only supports the old fields.

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.

This is a complete revamp of the original API. Some of the key
differences:
- refocused on structured parameters and allocating devices
- support for constraints across devices
- support for allocating "all" or a fixed amount
of similar devices in a single request
- no class for ResourceClaims, instead individual
device requests are associated with a mandatory
DeviceClass
For the sake of simplicity, optional basic types (ints, strings) where the null
value is the default are represented as values in the API types. This makes Go
code simpler because it doesn't have to check for nil (consumers) and values
can be set directly (producers). The effect is that in protobuf, these fields
always get encoded because `opt` only has an effect for pointers.
The roundtrip test data for v1.29.0 and v1.30.0 changes because of the new
"request" field. This is considered acceptable because the entire `claims`
field in the pod spec is still alpha.
The implementation is complete enough to bring up the apiserver.
Adapting other components follows.

This is in preparation for revamping the resource.k8s.io completely. Because
there will be no support for transitioning from v1alpha2 to v1alpha3, the
roundtrip test data for that API in 1.29 and 1.30 gets removed.
Repeating the version in the import name of the API packages is not really
required. It was done for a while to support simpler grepping for usage of
alpha APIs, but there are better ways for that now. So during this transition,
"resourceapi" gets used instead of "resourcev1alpha3" and the version gets
dropped from informer and lister imports. The advantage is that the next bump
to v1beta1 will affect fewer source code lines.
Only source code where the version really matters (like API registration)
retains the versioned import.

While currently those objects only get published by the kubelet for node-local
resources, this could change once we also support network-attached
resources. Dropping the "Node" prefix enables such a future extension.
The NodeName in ResourceSlice and StructuredResourceHandle then becomes
optional. The kubelet still needs to provide one and it must match its own node
name, otherwise it doesn't have permission to access ResourceSlice objects.
Kubernetes-commit: 0b6a0d686a060b5d5ff92cea931aacd4eba85adb
NodeResourceSlice will be used by kubelet to publish resource information on
behalf of DRA drivers on the node. NodeName and DriverName in
NodeResourceSlice must be immutable. This simplifies tracking the different
objects because what they are for cannot change after creation.
The new field in ResourceClass tells scheduler and autoscaler that they are
expected to handle allocation.
ResourceClaimParameters and ResourceClassParameters are new types for telling
in-tree components how to handle claims.
