Replace the single -checker-<id>-remote-address flag (which only
handled the endpoint case) with a generic per-option flag
-checker-<id>-<opt-id> registered for every AdminOpt declared by each
checker definition. Type-aware parsing (bool, float64, string) mirrors
how JSON-decoded options arrive at runtime.
