Looks like we compose metric name and lookup from REGISTRY every time, even
without executor ID and stream ID. I can see more calculation should be done
after addressing, but not sure how much it affects performance. If we could
also memorize metric name per combination of parameters it might help, but I'm
also not sure how much it will help.
Regarding issuing warning on name, +1 on your approach. Looks nice!
