fix(usage): tie usage to config

This starts us down the path of tying the params our commands accept to
their config items.  For now it is optional, and not every current
config item would cleanly render if we added them today.

The ones that are added here DO render nicely, and we can iterate from
here.  We can also at a later date do the same kind of appraoch with our
positional args.
