When using ember-holy-template-futuristic-template-namespacing-batman you
would often have addons that provide their own components without an app/
folder re-export (because why would you!?!?).
This transform traverses either addon/ (when ran within an addon's root
directory) or app/ (when within an application) and generates a valid
component file for each template only component found. This is basically the
same thing that ember feature:enable template-only would do internally, but
that functionality does not work for addons.
