refactor: replace User.objects.create_user for UserFactory p2

fix: Milestones app feature flag docs

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

ENT-4776

The feature flag that should be set is not ENABLE_MILESTONES_APP but
MILESTONES_APP.

doc: ADR for date override

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.

* fix: remove django-ipware constraint

- 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.

fix: add accent to e in resumé

refactor: send cert changed signal on_commit

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.

Toward MICROBA-1423

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:

[BB-4649] fix: Duplicate Arabic month

Description: Adds a new middleware to help with cookie name changes. It uses the idea of expand and contract, where after we've changed the name, the middleware allows up to accept either a cookie with new name (given higher priority when both are present) or cookie with old name.

This is also helpful when changing domain of a cookie.

impacts: developers, users(anyone that has cookies)
Change depends on django setting changes. See CookieNameChange middleware for more info.

fix: Fix bug where username is being used as DOM ID for accordian on bulk exam allowance view. (#28542)

MST-994

Fix the bug introduce when the username contains special characters like @. These causes javascript errors on bulk exam allowance view

The change is all on edx-proctoring library. This is a version update to fix the above bug

Once LOGIN_URL is changed for an environment, the OAuth flow will be
activated. (See included temporary doc.)

* fix: upgrade py2neo from 3.1.2 to 2021.1.5

The dump_to_neo4j management command has not been working
since the upgrade to python 3.8. The latest version of
python that py2neo 3.1.2 states support for is python 3.5,
so this isn't surprising.

The earliest non-prerelease version of py2neo that supports
python 3.8 is 2020.x (skipping the 4.x and 5.x series). Since
we're going as far as a 2020.x, we may as well upgrade all the
way to the newest series, 2021.x. This commit does that upgrade,
as well as a handful of minor code modifications in order
to handle breaking changes that have been made to the py2neo
API, and some unrelated pin bumps as the result of
'make upgrade'.

This will also require an upgrade of Coursegraph's Neo4j
version from 3.2.x to 3.5.x.
