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 * Be more selective about building all default keymaps * Update new-keymap to fit the new subcommand style * Add documentation about writing CLI scripts * Document new-keyboard * Update docs/cli_configuration.md Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com> * Update docs/cli_development.md Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com> * Update docs/cli_development.md Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com> * Update docs/cli_development.md Co-Authored-By: noroadsleft <18669334+noroadsleft@users.noreply.github.com> * Address yan's comments. * Apply suggestions from code review suggestions from @noahfrederick Co-Authored-By: Noah Frederick <code@noahfrederick.com> * Apply suggestions from code review Co-Authored-By: Noah Frederick <code@noahfrederick.com> * Remove pip3 from the test runner
