This change introduces the ability for the Kubelet to monitor and report
the health of devices allocated via Dynamic Resource Allocation (DRA).
This addresses a key part of KEP-4680 by providing visibility into
device failures, which helps users and controllers diagnose pod failures.
The implementation includes:
- A new `v1alpha1.NodeHealth` gRPC service with a `WatchResources`
stream that DRA plugins can optionally implement.
- A health information cache within the Kubelet's DRA manager to track
the last known health of each device and handle plugin disconnections.
- An asynchronous update mechanism that triggers a pod sync when a
device's health changes.
- A new `allocatedResourcesStatus` field in `v1.ContainerStatus` to
expose the device health information to users via the Pod API.

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.
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.
Now that they all call setup_env, we don't need find-binary (I think).
That was originally meant to hide the diff between docker and local
builds but all these tools do local builds anyway.
