by overriding can_load_courseware if the MFE is disabled for the user
If the user would be allowed to see the courseware MFE
(can_load_courseware), we check whether the MFE is disabled for them,
based on global settings, course settings (mongo courses), or their
particular bucketing in our ExperimentWaffleFlag.
If we determine they shouldn’t be allowed to see it, we return a new
CoursewareMicrofrontendDisabledAccessError access response, which the
MFE will use to know it should redirect to the old LMS experience.

The courseware_api view will use check_course_access - which now returns AccessResponse objects, and all other uses of check_course_access will now use check_course_access_with_redirect, which is a drop-in replacement for the original check_course_access implementation.
We also added a few new helpers to access_utils:
- check_public_access is a replacement for allow_public_access, which now returns AccessResponse objects
- check_enrollment checks if the learner is enrolled, and uses check_public_access to account for COURSE_ENABLE_UNENROLLED_ACCESS_FLAG
- check_survey checks whether there is a required survey that the learner must complete prior to accessing the course.
There are two new kinds of AccessError subclasses:
- SurveyRequiredAccessError
- EnrollmentRequiredAccessError
Content Type Gating: Xblocks that have a graded component cannot be
accessed by audit track users.
- Caveats:
- In studio, instructors can set certain xblocks to be available to
all users, but graded components will default to not being
available for audit users
- If a course does not have a verified mode option, all users will
have access to graded content.
The Waffle Flag: The waffle flag is of for now.
It's name is: ```content_type_gating.debug```
This Commit Does NOT Include: Displaying for a user WHY they do not have
access to a specific piece of content. That change will be part of
another PR.
