Logging: Inject

[loeffel-io]

It's almost disgusting how bad the logging is documented. There are several issues where people try to find a way to just add a single field from a grpc method to the logging finished call

Can please someone just document how to do this! I use the zap logger: https://github.com/grpc-ecosystem/go-grpc-middleware/blob/main/interceptors/logging/examples/zap/example_test.go

Hi Lucas. There is always room for better documentation, and I encourage you to dig in and contribute. The code in this repo is very shallow and simple, so it shouldn't be too hard to figure out the parts that you're wondering about. I'm not sure how to do this myself because I haven't had a need for this.
