This change will prevent Library Content from being marked as
complete on view and the corresponding version bump to
edx-completion contains code that will start looking at the
children of the library content for completeness.

Due dates will only display for graded subsections.
If the assignment has already been completed, there will be a pill
to indicate that. If the assignment is past due, there will be a
pill. If it is upcoming, there are no pills

As of Python 3.7, a backslash-character pair that is not a valid escape sequence now generates an error, earlier it was a deprecation warning.

Otherwise, these learners could start the timer and then be unable to take the exam once they have access to the content
REV-774

- Change cgi.escape to html.escape

- Add quote=False to html.escape

- Use function HTML() to address python-wrap-html warning

- yt_video_metadata returned a generic non-json-api-friendly 500 error
  when called on a non-youtube video
- load_metadata_from_youtube was crashing when called from the xblock
  yt_video_metadata endpoint. It passes a webob request, which has a
  different api for retrieving the http referer.

This should help more quickly narrow down where things are failing on an import.

We will now show the problem icon if the LTI problem
is scored and 'other' if it is not.

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.

This PR contributes to the elimination of deprecation warnings, specifically the one mentioned above and reported in the Warnings Report: https://build.testeng.edx.org/job/edx-platform-python-pipeline-master/warning_5freport_5fall_2ehtml/ .

Changed collection.find(filter).count() to collection.count_documents(filter) in the following file:

    common/lib/xmodule/xmodule/modulestore/tests/test_split_modulestore.py

And collection.find(filter).limit(1).count() to collection.count_documents(filter, limit=1) in the following file:

    common/lib/xmodule/xmodule/modulestore/mongo/draft.py

The method count_documents is part of the collection, not the cursor (find returns a cursor), according to StackOverflow (https://stackoverflow.com/questions/56303331/warning-message-in-pymongo-count-is-deprecated). Because of that after changing count, I removed the calling to the find method and use the filter parameter in count_documents. Also, I removed limit because count_documents accepts limit parameter.

This warning occurs due to deprecation: https://pymongo.readthedocs.io/en/3.9.0/api/pymongo/collection.html#pymongo.collection.Collection.count_documents

* Swap deprecated box-sizing mixin with the box-sizing property

* Linting now that box-sizing is no longer a mixin

Create a new plugin manager called DynamicPartitionGenerators to remove the dependency of openedx.features.content_type_gating by xmodule.partition_services

Improve accuracy of javascript-escape linter: Previously this would
match on FOOescape() and FOO.escape calls, but neither are the global
escape function we are worried about.

The regex probably isn't 100% accurate; there may be still false
positives (javascript allows a large range of characters in identifiers,
some of which may not be covered by [\w.$]). The main thing is to avoid
false negatives here though - this will definitely catch any use of
`escape()` or `window.escape()`.

Also remove javascript-interpolate lint - this was deemed unecessary.
StringUtils.interpolate is not in fact safe (it does no html escaping),
so the results of this lint are misleading.

In the course outline, if a subsection has any graded content,
show a graded icon (the pencil icon).

Also, show the graded icon for LTI xmodule units (xblocks is a
different repo, but will get same treatment).

During another bug investigation I figured there are some
issues related to showing error messages to learners upon
submission.

PROD-1431

Tests were failing due to the "404 Error" Response from an API that fetches specific asset (video transcript data) from YouTube.

I have changed it by using a mocked API response instead of direct API call to the Youtube server.

Replace some usage of deprecated assertions with non-deprecated equivalents.
