Swati Sehgal a311719d1e topologyupdater: Updates based on latest changes made to CRD API 
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/9
https://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.
