* First commit updating `config` to use subcommands (#2119) - Implemented `get` subcommand * Implmented `config set` as a subcommand. * Implemented `config set_into` as subcommand * Fixed base `config` command - Instead of outputting help, it now outputs the list of all configuration parameters. * Added `config clear` subcommand * Added `config load` and `config remove` subcommands * Added `config path` subcommand * fixed clippy
