* [fix] Fix certificate available date sync

We were syncing the course available date to every course in
credentials. Since credentials doesn't understand "self-paced" courses,
or course end behaviors, some certificates were time gated incorrectly.
This check make sure to check if the course is not self-paced, and has a
CDB of 'end' before syncing the CA date.

It's often very useful to note the reason we override a waffle.
Who asked for it and why - is it temporary until a feature is
completed or a complete opt-out of the feature itself, etc.

Now there's a text field to leave such comments for your future
self, much like waffle flags themselves.

We are planning on limiting session cookies for LMS, which
will mean that under the old cookie domain, MFEs and other
IDAs would not have access to the language preference of a user.

This moves language preference cookies to use a different setting,
which means that this cookie can be shared.

feat: send course access error along to course home MFE

chore: update edx-proctoring to 3.22.0

chore: update edx-enterprise

This completes the removal of unused fields in exam attempt,
so the migration test skip is no longer necessary.

fix: remove disabled v1 course certificate queue code

* fix: adding more parameters for cookie monitoring

Added: cookies_total_num, cookies_unaccounted_size. 
  -Both are to help us gauge how many cookies we are not collecting data for.
Increased: # of cookies data collected

This adds an `messages` field containing messages relevant
for configuring the provider to the DiscussionsConfigurationView.

feat: Third Party Auth - Boolean Enable Field for Enterprise Providers

feat: add boolean field to third_party_auth to be used to remove providers from enterprise selection

We previously only sent it to the courseware MFE. Also unify the
naming of this access error to 'course_access' in courseware and
course home APIs.

Add pinning test for SafeCookieData values, and update SafeSessions
middleware comments to match code.

Main comment changes:

- Fix description of cookie structure:
    - Specify hash algorithm (SHA256, not "H")
    - Don't try to describe internals of TimestampSigner; description was
      incorrect in several ways: Did not include string delimiters under
      base64 (there's JSON in there); did not include the actual MAC
      portion. Just describe general effect and shape of output.
    - Add missing trailing pipe delimiter in signed data hash input
- Use phrase "intermediate key" rather than the less familiar term "usage
  key"

Student name field is gone. This test was providing a blank name so nothing
more than delete is needed.

continuing sequence of DB migration releases

Problem blocks offer a setting to make users wait a set time between submissions. If a course is not authored in studio, it might not set a value for this setting. Consequently, the problem block must handle the submission_wait_seconds field to be none, so it doesn't break the submitted responses.

These kinds of errors here will prevent learners from submitting any answer, and has for several learners. Adding in this one-line change will prevent future errors without having to change the authoring practices of those ambitious enough to write their courses with import.

This also catches the case that some internal process other than studio might be creating problems with "none" as the setting.

In response to TNL-8234

Testing: hand-testing by importing the following problem xml file within a course and attempting to answer as learner(answer is 10.4).

* remove queue.py (and associated unit tests)
* remove references to `queue.py` from functions in api.py (also update unit tests)

Move cert display decisions to certificates app

fix: AA-912: Hide URL after due date if subsection is marked as hide …

When a sequence title was unavailable for a user (e.g. before starting a timed
exam), the `None` value was displayed in course breadcrumbs. This hides it in
such cases and ensures that a trailing breadcrumb separator is not displayed.

Signed-off-by: Farhaan Bukhsh <farhaan@opencraft.com>

A bug was reported of a learner accessing content that should have been hidden
due to the hide after due setting in Studio by the course team by clicking on
the Progress tab. This takes into account that value and will now hide the URL
on the Progress tab in that scenario.
