Show a link the courseware MFE to course staff if the ENABLE_COURSEWARE_MICROFRONTEND feature is enabled and the REDIRECT_TO_COURSEWARE_MICROFRONTEND CourseWaffleFlag is active for that course. Previously only global staff could see this link. This commit also adds ENABLE_COURSEWARE_MICROFRONTEND to lms/envs/common.py and makes this value True by default on devstack, since that front end application should soon be part of devstack: https://github.com/edx/devstack/pull/484 Related to TNL-6982 and TNL-7045.

The micro-frontend determines the user's position in the vertical via
|
|
a separate API call, so all we need here is the course_key, section, and
|
|
vertical IDs to format it's URL. For simplicity and performance reasons,
|
|
this method does not inspect the modulestore to try to figure out what
|
|
Unit/Vertical a sequence is in. If you try to pass in a unit_key without
|
|
a sequence_key, the value will just be ignored and you'll get a URL pointing
|
|
to just the course_key.
|
|
|
|
It is also capable of determining our section and vertical if they're not
|
|
present. Fully specifying it all is preferable, though, as the
|
|
micro-frontend can save itself some work, resulting in a better user
|
|
experience.

http://localhost:2000/course-v1:edX+DemoX+Demo_Course/block-v1:edX+DemoX+Demo_Course+type@sequential+block@19a30717eff543078a5d94ae9d6c18a5/block-v1:edX+DemoX+Demo_Course+type@vertical+block@4a1bba2a403f40bca5ec245e945b0d76
|
|

|
`course_key`, `sequence_key`, and `unit_key` can be either OpaqueKeys or
|
|
strings. They're only ever used to concatenate a URL string.
