Reduce logging noise

[nertzy]

Our logs are filling up with lots of repetitive noise:

I understand the value of being able to detect that Judoscale is sending metrics, but in my opinion this fits better at a debug log level.

Greetings @nertzy! 👋 Thanks for the PR!

Before chatting about the merits of whether those logs are more intrinsically "info" or "debug" logs, just want to check — have you adjusted the log level for Judoscale itself? https://github.com/judoscale/judoscale-ruby#configuration

# config/initializers/judoscale.rb
Judoscale.configure do |config|
  # ...

  # Change the log_level for debugging or to quiet the logs.
  # See more in the "logging" section of the README.
  # Default: (defer to underlying logger)
  config.log_level = :warn

  # ...
end

(or via JUDOSCALE_LOG_LEVEL=warn)

We know that folks have a lot of different logging desires and needs to we setup the Judoscale gem to follow a logging level independent from the underlying logger's level if the user/team desires.

@jon-sully that is an acceptable balance from my perspective. I will give it a shot! Thanks.
