refactor(usage): make usage declarations more programmatic

[wraithgar]

The next refactor for usage should be a more declarative approach. Instead of defining strings that show how to use certain params, each usage array entry should be a param and its description.

Usage output can then be npm command [list of params] followed by a description of each param we have defined.

This is the bridge between what we're doing now and a more tightly coupled definition of all our cli options and the commands that use them and the help sections for those commands.
