* Moving plugins infrastructure to edx-django-utils
This PR extracts the code that enables plugins in edx-platform and puts it in edx-django-utils. This is done to allow other IDAS to add plugin functionality.
The Randomized Content Block XBlock only randomizes the selection of
the children blocks and has unpredictable randomization of
the order of the selected child blocks due to the usage of sets, which
are unordered, for storing the selected blocks. This becomes apparent
when all the available child blocks in a library are chosen for a
Randomized Content Block, to randomize just the order of the child
blocks and not just the selection of the blocks. The order of the
selected blocks ends up being similar for multiple learners.
This change modifies the XBlock to store the selected child blocks in
a list, instead of a set, after randomly shuffling them.
A new block structure transformer, ContentLibraryOrderTransformer has
been added to transform the order of the selected children XBlocks to
match the order of the selections made in the
ContentLibraryTransformer. This ensures that same correct randomized order
of blocks is also returned by the course blocks API.
This version contains necessary fixes for validating the "audience"
component of the JWT, as seen in ARCHBOM-1281. (I believe we'll need to
pass both the App ID and the Service ID in an additional AUDIENCE "other
settings" key for this third-party-auth backend.)
Vendored from version 3.4.0 (9d93069564a60495e0ebd697b33e16fcff14195b)
social-core:
https://github.com/python-social-auth/social-core/blob/3.4.0/social_core/backends/apple.py
v3.4.0 is unreleased at this time (2020-07-28) and contains several
necessary bugfixes over 3.3.3 for AppleID, but also causes the
TestShibIntegrationTest.test_full_pipeline_succeeds_for_unlinking_testshib_account
test in common/djangoapps/third_party_auth/tests/specs/test_testshib.py
to break (somehow related to social-core's change 561642bf which makes
a bugfix to partial pipeline cleaning). ARCHBOM-1389 filed to address
this at our convenience.
Note: 3.4.0 was not released to PyPI due to a broken test, so we might
see a 3.4.1 when it's actually released:

This also has an initial use case for Personalized Learner Schedules
to add CTAs to capa and vertical blocks to allow users to shift their
course deadlines.
This reverts commit 06e04eff8c.
Omitting the course_key argument to ExperimentWaffleFlag.is_enabled
causes a 500 when the underlying experiment flag is enabled.

We noticed that since users can choose to reset their due dates,
they would have the ability to let due dates pass and then for any
assessment that allows viewing the answer after the due date would be
visible. The user could thus view all answers and then reset their
due dates to receive a perfect score.
This PR works to fix that issue by changing all show answer values
to not take into account being past the due date when inside a PLS
course.
