The runtime classes are apiserver's concept, while the handlers are kubelet's concept.
For NodeStatus, it makes more sense to return the latter ones here.
This commit modifies the following files:
- pkg/apis/core/types.go
- staging/src/k8s.io/api/core/v1/types.go
- pkg/kubelet/nodestatus/setters.go
- pkg/kubelet/kubelet_node_status.go
- pkg/registry/core/node/strategy.go
- test/e2e_node/mount_rro_linux_test.go
Other changes were auto-generated by running `make update`.

Previously we were returning the error string from 'err' (which is nil), when
we should have been returning it from result.Error. Without this it is hard to
debug issues with NodeUnprepareResources.

The map is changed to an array so as to retain the order of the original array
propagated from the CRI runtime.

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.
The information is received from the DRA driver plugin through a new gRPC
streaming interface. This is backwards compatible with old DRA driver kubelet
plugins, their gRPC server will return "not implemented" and that can be
handled by kubelet. Therefore no API break is needed.
However, DRA drivers need to be updated because the Go API changed. They can
return
status.New(codes.Unimplemented, "no node resource support").Err()
if they don't support the new ListAndWatchResources method and
structured parameters.
The controller in kubelet then synchronizes this information from the driver
with NodeResourceSlice objects, creating, updating and deleting them as needed.
If the resource handle has data from a structured parameter model, then we need
to pass that to the DRA driver kubelet plugin. Because Kubernetes uses
gogo/protobuf, we cannot use "optional" for that new optional field and have to
resort to "repeated" with a single repetition if present.
This is a new, backwards-compatible field.
That extending the resource.k8s.io changes the checksum of a kubelet checkpoint
is unfortunate. Updating the test cases is a stop-gap measure, the actual
solution will have to be something else before beta.
See https://github.com/golang/mock#gomock: golang/mock is no longer
maintained, and should be replaced by go.uber.org/mock.
This allows golang/mock to be dropped from the status and vendored
fields in unwanted-dependencies.json.

The kubelet watches services only to generate the environment variables
inside a pod, but headless services are not needed for this.
