We now have metrics for getting detailed information about the NFD instances running. There should be no need to pollute the node object with NFD version annotations. One problem with the annotations also that they were incomplete in the sense that they only covered nfd-master and nfd-worker but not nfd-topology-updater or nfd-gc. Also, there was a problem with stale annotations, giving misleading information. E.g. there was no way to remove old/stale master.version annotations if nfd-master was scheduled on another node where it was previously running.
