-  This PR removes all imports from provider by either bringing them into edx-platform or finding dot replacement. Removing tests that tested dop parts of code. 

-  Skipping some tests and removing dop

The tests are difficult to fix due to its entanglement with dop use in third_party_auth.
These tests should be restarted once dop has been removed from third_party_auth and its tests.

BB-986: Add variable that allows overriding marketing urls

Re-enable caching of context processor output

Relates to TNL-7076

- Reimplement `djcelery.common.respect_language` utility function so we
  can drop the dependency.
- Loosen `celery` pinning to a range, which brings in a fix for a
  possible crash bug

Also, pin `path` to 13.1.0 for now in order to continue supporting py35.

In Django template rendering, context processors only run once.
But when we do template rendering through edxmako (which we do for
each and every web fragment/XBlock), we can end up having hundreds
of invocations of templates and run context processors for each
separately. This removes that work.

This was originally added in ad5cc3d5 and reverted when we saw
errors in one of our environments that seemed to be related to
context processor code. Those errors persisted after the revert,
and so I'm adding this back in (with some modifications based on
review comments).

This commit adds a feature that allows overriding any marketing URL, either by configuration on lms.env.json or SiteConfiguration, regardless if a marketing website is set up.
The links can be set by passing MKTG_URL_OVERRIDES to either `lms.env.json` or `SiteConfiguration`.

Show due dates self paced from edx when

Moves the existence check for secondary (recovery) email to validate
method. If the email already exists, silently remove it from the set of
data to be updated. This parallels the existing behavior for updating
the primary email.

BOM-1324: add constraint for edx-drf-extensions

Add DOP adapter setting to production.py so it can be overridden.

Learning MFE URL should not have a slash

Revert "Allow due-dates for self-paced courses in the course outline"

This will ultmately be put back in as part of TNL-6982, but for now we don’t want this code to be associated with the waffle flag.

There is a planned edx-drf-extension update to 3.0.0 to remove the
toggle used for ENFORCE_JWT_SCOPES. Currently, edx-platform is dependent
on the this toggle. This constraint will keep other `make upgrade` PRs
working in the short window before the edx-paltform PR to remove the
same toggle can land.
