Offers blockstore-based content through content libraries acting as an
LTI 1.3 tool:

- Content Library support LTI 1.3 launches offering blockstore-based
  content through resource links.

- Content Library support LTI 1.3. AGS, allowing gradebook updates from
  graded assignments.

feat: `djang-cor-headers` need schemes with urls. Adding condition to switch lists with different version.

With the PR it will load the old `CORS_ORIGIN_WHITELIST` since there is no change in `djang-cor-headers` version. In next PR this version will get upgraded.

In the PR https://github.com/edx/edx-platform/pull/10659 the outer_atomic decorator/context manager was created to prevent nested atomic blocks. This method received a boolean parameter read_committed to enforce read-committed MySQL isolation level. From Django 2, the default isolation level Django sets is read-committed, so the aforementioned parameter for outer_atomic can be removed

This change is done so the profile is automatically created for tests users

In the case where a server/course has both:

* YouTube deprecated (waffle flag: videos.deprecate_youtube = True)
* HLS enabled (ConfigModel: HLSPlaybackEnabledFlag, in video_config)

Prior to this commit, we would prefer the HLS source if one of the
HTML5 video sources specified a .m3u8 file. However it looks like this
file isn't always guaranteed to be produced.

This fix always prefers HTML5 video sources to YouTube if the server or
course is configured to deprecate YouTube, as long as at least one
non-YouTube source is found. TNL-8594.

Note that this may confuse users because we're essentially bypassing
their Studio-specified preferred primary source with a server-wide
setting.

- Removed manage_user and manage_group commands and their unit tests from edx-platform and added then to edx-django-utils.
- Modified User.post_save signal to ensure the user profile is created when manage_user management command is run to create a user.
- Added edx-django-utils to INSTALLED_APPS for LMS and Studio.
- Moved generate_password from openedx.core.djangoapps.user_authn.utils to edx_django_utils.user along with its unit test.

MST-805. A signal should be emitted upon an IDV attempt being submitted or reviewed for consumption by other applications.

Because we have ATOMIC_REQUESTS turned on, the COURSE_CERT_CHANGED
signal was being sent *before* the date override was committed to the
database. This means that the date override data sent to credentials on
CertificateDateOverride save() was always one commit behind.

Django provides an on_commit() function to allow us to perform actions
only after a transaction is completed successfully. I believe this
is when we want this signal to be sent.

This is an alternative to 1) disabling atomic transactions for a view
(honestly, I’m not sure which view we would target anyway), or 2)
passing more data down through the signal.

This also requires using different session cookie names in devstack for
LMS and Studio so that we can properly use the OAuth flow locally, rather
than just sharing a session cookie on the localhost domain. (Note that
ports are not used for cookie segmentation in browsers.)

This depends on the following provisioning PR:

Fixes: REV-2214

If a user with staff access is masquerading as a specific student, they should be able to see content that would normally be gated for that student.

* Add unsubscribe_token uuid field to CourseGoal model
* Add endpoint to unsubcribe from just a token (no login needed)
* Add admin page for the course_goals djangoapp
* Add get_course_overview_or_404 utility method
* Clean up URL handling in course_home_api

block_type isn't guarantee to be the same as item_type. In this case, item_id should be enough for filtering.

Ticket [AU-70]

[MICROBA-1412]
[DEPR-155]

Remove the request_certificate REST endpoint from the LMS (certificates Django app)

The proctored exam settings link now directs to a new modal view, rather
than the old exam settings page.

Certificate tests required an update to switch from boolean verified
flag to status. This feature is not deployed yet so only test uses
needed attention.

MST-969 and friends

When sending a GeneratedCertificate to Credentials, send the associated
CertificateDateOverride (if there is one), or else None. This
will be triggered after any save of a GeneratedCertificate, and after
any save or deletion of a single CertificateDateOverride.

Credentials will eventually store its own copy of this date override, or
edit or remove exiting date overrides.

Remove the waffle flag for bulk allowance, so by default the bulk allowance feature is enabled and is the only option.
