NodeResourceTopology(aka NRT) custom resource is used to enable NUMA aware Scheduling in Kubernetes.
As of now node-feature-discovery daemons are used to advertise those
resources but there is no service responsible for removing obsolete
objects(without corresponding Kubernetes node).
This patch adds new daemon called nfd-topology-gc which removes old
NRTs.
