feat(cli): Add CLI support for RevPi configuration object (revpi-config)

This implements a new command "config" in the CLI to handle RevPi
configuration. It includes parsing and subparser setup for
configuration-related operations. The change improves usability by
extending CLI functionality to manage RevPi configuration objects.
