AA-454 and AA-470: Update language and bug fix for highlights

Revert "ARCHBOM-1636: upgrade supercsv"

Since Course Highlights aren't necessarily weekly (self-paced courses),
update the language to be more generic. And then includes a bug fix to
not send highlights to learners after they have unenrolled from a course.

If ORGANIZATIONS_AUTOCREATE, this will create a new
org in the case that the organization is missing.

If !ORGANIZATIONS_AUTOCREATE, this will raise a
validation error in the case that the organization is
missing.

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`).
