POC: Puma Worker Killer based on requests count

[ylecuyer]

This is a proof of concept based on puma/puma#2106
It mimics the PassengerMaxRequests configuration of passenger : https://www.phusionpassenger.com/library/config/apache/reference/#passengermaxrequests and kills workers after 10k requests

Here is a demo: https://youtu.be/ZUho9KCQGXk

Can you tell me more about the desire here? I think this can be implemented better as a separate middleware. Basically in the middleware you can simply exit(1) or raise a sigterm in the existing process, then puma will bring it back up. My preference would be to not add this directly to puma worker killer. If you make another gem, then I can link it in the README.
