Fixed duplicate asset on creating rerun

Certificates API is retuning 500 error for old XML courses in which learners
have a valid certificate.

PROD-1247

Remove duplicate constraints in requirements/constraints.txt uncovered by the recent change in pip-compile output format. I sorted the pinned dependencies by name to try and make it more obvious if this happens again. I also upgraded to pip-tools 4.5.1, which removes the line numbers from the enhanced pip-compile output added in 4.5.0, which should reduce future diff churn and merge conflicts but means that there's a large diff this one last time.

Also unpin edx-search again after the previous change to do that was apparently broken by a merge conflict.

Rename values in SiteConfiguration (2/3)

-  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).
