Markus Lehtonen f13ed2d91c nfd-topology-updater: update NodeResourceTopology objects directly
Drop the gRPC communication to nfd-master and connect to the Kubernetes
API server directly when updating NodeResourceTopology objects.
Topology-updater already has connection to the API server for listing
Pods so this is not that dramatic change. It also simplifies the code
a lot as there is no need for the NFD gRPC client and no need for
managing TLS certs/keys.

This change aligns nfd-topology-updater with the future direction of
nfd-worker where the gRPC API is being dropped and replaced by a
CRD-based API.

This patch also update deployment files and documentation to reflect
this change.
