metrics-server can target Puma
In &6409 (closed) we introduced a mechanism to spawn a dedicated metrics server process from Sidekiq via the metrics_server
module. It was written in a way to be agnostic of what it is monitoring, but we never tested it with Puma and there will be some fixes necessary for it to actually work.
This issue will focus mainly on this sort of clean-up without actually activating the server process yet.
