Bump cpuid version to v2.2.4 in the go.mod so that WRMSRNS (
Non-Serializing Write to Model Specific Register) and MSRLIST
(Read/Write List of Model Specific Registers) instructions are
detectable.

The NodeResourceTopology API has been made cluster
scoped as in the current context a CR corresponds to
a Node and since Node is a cluster scoped resource it
makes sense to make NRT cluster scoped as well.

There have been recent changes made to the noderesourcetopology API
storing the proto file generated using go-to-protobuf tool and
this code inports the proto generated in the API in the topology-updater.proto
The PRs corresponding to the changes are as follows:
https://github.com/k8stopologyawareschedwg/noderesourcetopology-api/pull/9https://github.com/k8stopologyawareschedwg/noderesourcetopology-api/pull/13
Commands used to generate topology-updater.pb.go file:
go install github.com/golang/protobuf/protoc-gen-go@v1.4.3
go mod vendor
protoc --go_opt=paths=source_relative --go_out=plugins=grpc:. pkg/topologyupdater/topology-updater.proto -I. -Ivendor
As part of implmentation of this patch, reserved (non-allocatable) CPUs
are evaluated by performing a difference between all the CPUs on a system
(determined by using ghw) and allocatable CPUs (determined by querying
GetAllocatableResources podResource API endpoint).
When aggregator creates the NUMA zones, it will skip the zone creation if
there are no allocatable resources. In this update we creates those missing
zone with zero allocatable/available resources so we won't have holes in the
array of reported zones.

- This patch allows to expose Resource Hardware Topology information
through CRDs in Node Feature Discovery.
- In order to do this we introduce another software component called
nfd-topology-updater in addition to the already existing software
components nfd-master and nfd-worker.
- nfd-master was enhanced to communicate with nfd-topology-updater
over gRPC followed by creation of CRs corresponding to the nodes
in the cluster exposing resource hardware topology information
of that node.
- Pin kubernetes dependency to one that include pod resource implementation
- This code is responsible for obtaining hardware information from the system
as well as pod resource information from the Pod Resource API in order to
determine the allocatable resource information for each NUMA zone. This
information along with Costs for NUMA zones (obtained by reading NUMA distances)
is gathered by nfd-topology-updater running on all the nodes
of the cluster and propagate NUMA zone costs to master in order to populate
that information in the CRs corresponding to the nodes.
- We use GHW facilities for obtaining system information like CPUs, topology,
NUMA distances etc.
- This also includes updates made to Makefile and Dockerfile and Manifests for
deploying nfd-topology-updater.
- This patch includes unit tests
- As part of the Topology Aware Scheduling work, this patch captures
the configured Topology manager scope in addition to the Topology manager policy.
Based on the value of both attribues a single string will be populated to the CRD.
The string value will be on of the following {SingleNUMANodeContainerLevel,
SingleNUMANodePodLevel, BestEffort, Restricted, None}
