[bug][2.0] conan config list prints to stderr

Environment Details (include every applicable attribute)

• Operating System+version: Ubuntu 22.04
• Compiler+version:
• Conan version: 2.0.0-beta3
• Python version:

Steps to reproduce (Include if Applicable)

conan config list prints all available config options to stderr instead of stdout. That makes it difficult/annoying to e.g. grep for options.

Just bumped into this and would also like to point out that the output of conan config list is essentially the same as the json output, with the exception that the text output contains Supported Conan global.conf and [conf] properties: which I think should go to conan config list --help. After you’ve run that command once you know what it does and you don’t need the manual to be printed every time. Imagine if git config --list would begin it’s listing with Current git configuration settings: or something.

I’d say the most intuitive way would be to keep the default listing 1-to-1 with other stable formats and add additional flags to make it look nicer. Again with the git examples: git log vs git log --oneline --graph. The current output is pretty readable as it is, but if you want to support easier grouping, add an optional globbing pattern: conan config list core.* and so on, but please don’t make the customized special case output the default.

I agree, those explanations can be removed. We have fixed it in https://github.com/conan-io/conan/pull/12235, removing those things too, but if there are still some pending or a new one appears, please submit a new issue, or create a PR to remove it. Thanks!
