Config: Add override argparser

Add an argparser that casts over to dictionaries of subgroups to
integrate with the config.

This argparser doesn't contain everything in the config due to complexity
issues with CLI args, but will eventually progress to parity. In addition,
it's used to override the config.yml rather than replace it.

A config arg is also provided if the user wants to fully override the
config yaml with another file path.
