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.

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.
Align "topologyupdater" overlay with "topologyupdater-job". Both should
deploy topologyupdater as a standalone application. Previously the
topologyupdater overlay did not deploy nfd-master at all (but deployed
nfd-worker instead) causing the pods to end up in crashloopbackoff as
there was no master to communicate with.
- create an overlay for deployment of all components
- create an overlay for just topologyupdater deployment (to be deployed in
conjunction with the default overlay)
- create a separate overlay for deployment of master and topologyupdater-job
