This reverts commit c94abd27.

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.

* Add a new cookie for user information
* Make marketing cookie names configurable.
* Handle URL reversal when URLs don't exist (in Studio)
* Move cookie code from student/helpers.py into its own module.

Also moves the default icons to the badges subfolder to avoid storage conflicts.

Use native checkboxes for courseware license options
In Studio settings editor for video module, don't show license if feature-flagged off
Don't let Scope.contents fields leak to Studio editor
JS gettext() must all be on the same line for i18n
Add docstrings for bok-choy tests
Remove LicenseMixin from HTMLDescriptor
Responding to UX review feedback
Add aria-pressed attribute
Use https links instead of protocol-relative links for links to creativecommons.org
Remove license from course outline page in Studio

Added setting to enable/disable library indexing + moved is_index_enabled into search indexer classes
Added task and signal to fire library reindex

The replacement strings need to be unicode, so that when STUDIO_NAME contains non-ascii characters python can handle it correctly without raising exceptions.
Also, the value of STUDIO_SHORT_NAME can be read from cms.env.json.

This makes these files importable, and puts them into the new best guess
as to where files should live.

path.py objects report themselves as class objects, which confuses the heck out of
pylint. It tries to match variable names using the class-rgx regular expression
instead of the constant-rgx regular expression, and it doesn't match, so it
throws an error. Not sure how to fix pylint, so we'll just ignore these errors.

This feature allows upload of video assets to S3. This requires that the
VIDEO_UPLOAD_PIPELINE setting be properly configured and that each
course be configured with a token issued by the media team for their
processing purposes (e.g. linking the video with a YouTube channel).

    Modified to a setting in CMS common.py and aws.py
    Also factored out are: ADVANCED_PROBLEM_TYPES

    This enables third parties to add XBlocks to their system
    without having to make a code change.

    Code also added to ensure that a component should exist in both
    ADVANCED_COMPONENT_TYPES and the course advanced module list
    in order for it to be enabled in the course.

This is not currently being used in production and will not
be used moving forward since logs are remoted using splunk
