Add toggle to remove access to DOP code paths.

Fix constraints to not have a lingering pin on edx-when. And
add constraint on version of mock that supports python 3.5.

And then a general make upgrade.

Add course_date_signals to INSTALLED_APPS

* Added new auth class

- Created new class called OAuth2AuthenticationAllowInactiveUser, which replaces old class with same name
- Renames previous  OAuth2AuthenticationAllowInactiveUser to  OAuth2AuthenticationAllowInactiveUserDeprecated
- Replaced all imports of  OAuth2AuthenticationAllowInactiveUser to call deprecated class instead
- testing new class in discussion(added flag based on django setting)

Correctly wire in signal the new course_date_signals app so that it a…

Fixed the most frequently occurring deprecation warnings, which were causing over half of the 34,140 deprecation warnings raised during the unit tests:

* `Use of .. or absolute path in a resource path is not allowed and will raise exceptions in a future release` - most of these were due to a single mis-configured resource path with a leading slash.
* `count is deprecated. Use Collection.count_documents instead.` - I added a handful of simple workarounds for this pymongo deprecation that shouldn't increase the query counts

Also did some cleanup of unused code in pavelib after the recent split of the new `i18n_compilejs` command from `i18n_dummy`. (This had caused a diff-quality failure on the first commit.)

Remove ENABLE_SQL_TRACKING_LOGS and all associated code.

Reveal a message to be extracted

Remove the tracking django backend and the TrackingLog tables.

Adds compilejs task to paver.

ENT-2604: Updated edx-enterprise version

BOM-897

* Added new authentication class(meets drf standards)

The new class replaces the deprecated oauth2authetnication class from rest_framework_auth library(repo django-rest-framework-oauth).
Majority of the code is combination of copy-pasta from old oauth2authentication class and Oauth2AuthenticationAllowInactiveUser class

* Added ability to switch to new authentication class in bookmarks app

* Changed error type reported by Outh class. It now outputs a json rather than a string.

Previously, we'd show three layers deep (section, subsection, and
unit). But now we cut out unit and stop at subsection.

 BOM-897: add course_ids api

Add unique_together on course_uuid and order_number to avoid
duplicate records

PROD-1064

Adds a course_ids api that can filter by user role, since the courses
api could not perform well enough for this, and returned much more
data than we need.

Additionally, adds a LazyPageNumberPagination to provide more accurate
counts in the pagination response when using LazySequence with the
queryset.
