Setup the topologyupdater API for gRPC communication of
nfd-topology-updater with master
We generate pb.go file to reflect latest dependency changes
using github.com/golang/protobuf/protoc-gen-go and generate
grpc files via:
`protoc pkg/topologyupdater/topology-updater.proto --go_out=plugins=grpc:.`
Please refer to: https://github.com/k8stopologyawareschedwg/noderesourcetopology-api/blob/master/pkg/apis/topology/v1alpha1/types.go

When updating node labels and annotations use JSON patches instead of
doing a read-modify-write on the whole node object. Patching is already
being used in managing extended resources so some of the existing code
was re-usable.
This patch should mitigate the problem of node update failures caused by
race conditions (a change in the node object between our read and write)
resulting e.g. in errors/restarts in nfd worker pods.
A new sub-command like flag for cleaning up a cluster. When --prune is
specified nfd-master removes all NFD related labels, annotations and
extended resources from all nodes of the cluster and exits.
This should help undeployment of NFD and be useful for development.
This adds support for making selected labels extended resources.
Labels which have integer values, can be promoted to Kubernetes extended
resources by listing them to the added command line flag
`--resource-labels`. These labels won't then show in the node label
section, they will appear only as extended resources.

Refactor NFD into a simple server-client system. Labeling is now done by
a separate 'nfd-master' server. It is a simple service with small
codebase, designed for easy isolation. The feature discovery part is
implemented in a 'nfd-worker' client which sends labeling requests to
nfd-server, thus, requiring no access/permissions to the Kubernetes API
itself.
Client-server communication is implemented by using gRPC. The protocol
currently consists of only one request, i.e. the labeling request.
The spec templates are converted to the new scheme. The nfd-master
server can be deployed using the nfd-master.yaml.template which now also
contains the necessary RBAC configuration. NFD workers can be deployed
by using the nfd-worker-daemonset.yaml.template or
nfd-worker-job.yaml.template (most easily used with the label-nodes.sh
script).
Only nfd-worker currently support config file or options. The (default)
NFD config file is renamed to nfd-worker.conf.
