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.
