How to quiet access logs?

[stevefolly]

How can I turn off request logging from the plugin's Rack app? I don't particularly need to see ... GET /metrics ... every minute in my Rails logs.

It took me a while to work out standard Puma config in config/puma.rb to quiet requests wasn't having any effect because the plugin creates its own Rack app!

I managed to prove it works by editing yabeda_prometheus.rb and adding log_writer: Puma::LogWriter.null as an argument to Puma::Server.new. Is that the best way, or is there another, less intrusive way to do this?

Would you accept a PR to make this configurable from config/puma.rb?

Thanks
