Public Course Import/Export API

ziafazal/SOL-980: Generate certificates from instructor dashboard

Credit requirement optimizations

Credit eligibility/provider refactor

This feature flag gates the exposure of the Full course/library
Import/Export API URLs in the LMS. This allows openedX deployments
that operate without Studio to take advantage of the API, while
others may turn the feature off to reserve all content authoring for
Studio.

This is a public, versioned, RESTful API for importing and
exporting full course content. The code was initially ripped from the
existing import/export API in the CMS contentstore djangoapp and wrapped
in Django Rest Framework view classes. It's a new djangoapp in
the openedx directory which is largely an abstraction off the CMS
Import/Export views.

This PR includes configuration changes. Most notably, Studio is
configured to serve the OAuth2 provider alongside the LMS.

This is the initial thread on the code list:
https://groups.google.com/forum/#!msg/edx-code/DmnHWmly25A/ZqjD1zb4o7oJ

And this thread contains another description of the changes:
https://groups.google.com/d/msg/edx-code/6dP9SEKsmqQ/Pvyn8fBDx68J

There are a numerous non-covered lines, all of which are missing
coverage in the CMS API this was ported from. They're mostly error
conditions, such as handling of multipart file upload errors.
