This looks good @SomtochiAma (and thanks @rajansandeep for the reviews!).

I apologize for this, but we should figure out what name we want to use. I think the most common terms were LocalNodeDNS or LocalNodeDNSCache based on some basic google searching; but if we can justify the existing name then that's fine too!

Thanks for renaming - for other tweaks (e.g. sharing functions that you've now put into the kubebuilder-declarative-pattern library :-) ) I think we can merge + iterate
