thanks @eduwercamacaro

I wrote a test that verifies that metrics are published: https://github.com/apache/kafka/pull/20570/files#diff-a8f919d43ec1cebdb136acf94adfbeb20fef0cda0ad5d29b7010e0186b355d71
I tired to run it with this change, but, unfortunately, it didn't work, and I couldn't quickly figure out why...
just a heads-up

Hi @Nikita-Shupletsov Thanks for your time checking these changes. 😄

Unfortunately, this PR contains too many changes that I need to clean up, and it is not particularly easy to follow. I am working on some cleanups to make it easier to read.

Thank you for pointing out the integration test. If possible, I'll try to make these changes pass after the cleanup.
