* Adds a credit course mode to indicate that a course
has a credit option.
* Hides the credit option from the track selection and
pay-and-verify pages.
* Shows different messaging for the verified track if
it's possible to upgrade from verified to credit at the end
of the course.
This commit updates common/djangoapps.
These keys are now objects with a limited interface, and the particular
internal representation is managed by the data storage layer (the
modulestore).
For the LMS, there should be no outward-facing changes to the system.
The keys are, for now, a change to internal representation only. For
Studio, the new serialized form of the keys is used in urls, to allow
for further migration in the future.
