Configuration system for CLI (#6708)

* Rework how bin/qmk handles subcommands

* qmk config wip

* Code to show all configs

* Fully working `qmk config` command

* Mark some CLI arguments so they don't pollute the config file

* Fleshed out config support, nicer subcommand support

* sync with installable cli

* pyformat

* Add a test for subcommand_modules

* Documentation for the `qmk config` command

* split config_token on space so qmk config is more predictable

* Rework how subcommands are imported

* Document `arg_only`

* Document deleting from CLI

* Document how multiple operations work

* Add cli config to the doc index

* Add tests for the cli commands

* Make running the tests more reliable

* Update new-keymap to fit the new subcommand style

* Add documentation about writing CLI scripts

* Document new-keyboard

* Update docs/cli_configuration.md
