AA-454: Reenable CourseUpdateResolver for Instructor-paced Courses

Remove unnecessary and misleading data-rel attributes

When CourseNextSectionUpdate was created, it incorporated Personalized
Learner Schedules logic which didn't take into account release dates of
content and was only intended for self-paced courses that always have
all content released. This caused a bug where instructor-paced courses
could receive an update about content that had not been released yet.

This PR turns the CourseUpdateResolver back on for instructor-paced
courses so they can go back to receiving weekly highlights.

[BD-21] Start waffle namespace deprecation process

Waffle classes no longer have namespaces. All features are moved to the
WaffleFlag/WaffleSwitch classes.

Here we use the edx_toggles.toggles.__future__ API, which is available
in 1.2.0. This means that we don't have to upgrade edx-toggles. We
should remove the __future__ imports as soon as we upgrade to 2.0.0.

This is required because edx-platform uses the waffle API from
completion, which itself depends on edx-toggles. So if we change
edx-toggles import paths, we also need to upgrade our usage of
completion here.

By explicitly importing the legacy namespace classes, we make it clear
that we are using soon-to-be-deprecated classes. We will then be able to
start removing the legacy classes, one module at a time.

ARCHBOM-1636

* Install `organizations` app into LMS and Studio non-optionally.
* Add toggle `ORGANIZATIONS_AUTOCREATE` to Studio.
* Remove the `FEATURES["ORGANIZATIONS_APP"]` toggle.
* Use the new `organizations.api.ensure_organization` function to
  either validate or get-or-create organizations, depending
  on the value of `ORGANIZATIONS_AUTOCREATE`,
  when creating course runs and V2 content libraries.
  We'll soon use it for V1 content libraries as well.
* Remove the `util.organizations_helpers` wrapper layer
  that had to exist because `organizations` was an optional app.
* Add `.get_library_keys()` method to the Split modulestore.
* Add Studio management command for backfilling organizations tables
  (`backfill_orgs_and_org_courses`).

DEPR-43 - Removal of Shoppingcart.

All models have been removed and the change has been deployed to production
so this should be safe to do.

It's strange that the ORM decided to drop certain fields before dropping the
whole models but decided to leave it all as the ORM generated it rather than
trying to manually change it.

Also turn the check back on to make sure people don't actually check in code
without the relevant migration files.
