This class only served one purpose, to avoid typing the name of the
option twice. Unfortunately the way it was implemented made getting the
type checking right difficult, and required storing the same data twice.
This patch replaces this approach with a dictionary comprehension that
creates the OptionKey from the UserOption. This allows us to initialize
a single dictionary once, avoid typing the name twice, delete lines of
code, and get better type safety.
As an added bonus, it means that the exported data from the module can
be marked module constant, ie, ALL_CAPS.
