Viktor Barzin 6ee283c2f0 [docs] Document external-monitor opt-out mechanism in monitoring.md 
The doc said monitors were created for everything in cloudflare_proxied_names,
but since the k8s-api discovery rewrite the ConfigMap is a fallback only.
Describe the opt-OUT semantics and how external_monitor=false on a factory
call translates to the sync script's skip annotation.
