PS1: Honestly, this looks overengineered to me. Especially the `Info` class, which is a `Warning` but not really a warning. Why not using the standard logging module, which does have all the necessary facilities (logging categories, logging targets, etc.)? You can then define a logging target that prints messages using `cmd2`.
