Add JSON-structured console logging

[Exctues]

Currently I see that JSON structured logging is implemented for files (which is amazing), but not for console (stdout)

I think it would be amazing to be able to to choose between logging structured-json in either file or stdout out of the box!

Thanks for consideration!

This would make structured logging in k8s or any other system that collects logs from the console much easier.
