Only actually reset user schedule if they have missed deadlines and not missed any gated content deadlines

Removed the FakePaymentPage page object which used shoppingcart app functionality, as well as everything that depended on it. I checked the e2e test repo also, and it doesn't seem to need any of the removed code.

This patch improves on the user locked
out logic by providing a helping message
near locked out. This would help reduce
retries by giving user the option to use
password reset flow to fix the issue.

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.

Use a fixed time for course duration limits, so that schedule extensions don't extend FBE duration limits

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.

Remove all references to the shoppingcart app from the course about page. Also removed one test of shoppingcart functionality from the student app.

Add list of states and field to UserProfile model; add migration; add
state field to relevant serializers and to
ACCOUNT_VISIBILITY_CONFIGURATION. Removes state data if country is
changed to something other than United States.

Rather than fetching the Site for every provider in a loop, just look at
the ID of the site.

Added regression test, showing N `django_site` requests before and 0 after.

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

Enhance the Link Program Enrollments Support Tool to handle the case of linking a learner to a ProgramEnrollment that is already linked to a different edX account.

In this case,
* unenroll the currently linked learner from the courses associated with related ProgramCourseEnrollments
* for each course the is enrolled in as part of a ProgramCourseEnrollment, if the coures has an audit track, then move the enrollment into the audit track. Otherwise, keep the learner's enrollment in the existing track.
* link the new user to the ProgramEnrollment
* enroll the new user in the Master's track in the courses associated with related ProgramCourseEnrollments
