Add a minimal option to pylint --generate-toml-config

[cclauss]

Current problem

pylint --generate-toml-config can produce 500+ lines of TOML config and comments. This is a lot of text to understand, search, and edit compared to the configuration of other tools. Can we create a far less chatty version pylint --generate-toml-config that strips all settings that match the pylint default and all nonessential comments.

Desired solution

A default value trimmer could be used to slim down existing TOML configurations and/or be run as a post-process to pylint --generate-toml-config.

Additional context

pylint-dev/astroid#1793

This will be available with #7489

It can be invoked with pylint-config generate --interactive.
To take a previous rcfile into account use pylint-config --rcfile=MYFILE generate --interactive

Can we please reopen this issue?

I did pylint-config --rcfile=pylintrc generate --interactive . in the astroid repo and selected t and my_file.toml. The result was a 551-line file which is clearly not what this issue was targeting. The file was chock full of comments and default values and ended with three blank lines which will trigger other pre-commit tools like end-of-file-fixer.

Did you use the version on the main branch? The PR that fixed this was not back ported to the just released version as it contained a new feature. We only put fixes in the patch releases to guard against potential new regressions in new features.
