This is a first stage for removing the LegacyWaffle* classes.
LegacyWaffleFlag usage replaced with WaffleFlag;
LegacyWaffleSwitche usage replaced with WaffleSwitch;
New CourseWaffleFlag added to the temporary module __future__ as FutureCourseWaffleFlag;
Updated all the imports to use CourseWaffleFlag from the __future__ module;
BREAKING CHANGE: A number of toggle related constants (e.g. ENABLE_ACCESSIBILITY_POLICY_PAGE)
changed types. They were strings, and are now toggle instances (e.g. WaffleSwitch). Although the entire
refactor should be self-contained in edx-platform, if any plugins or dependencies were directly
using these constants, they will break. If this is the case, try to find a better publicized way of
exposing those toggles.
A variety of updates were made to improve the toggle documentation:
* Added comments to help ensure that the waffle(), waffle_switches(),
waffle_flags() anti-pattern won't be contagious (copied).
* Some minor toggle_description updates.
* Removed empty toggle_target_removal_date annotations for
non-temporary toggles.
* Removed empty optional toggle_warnings annotations.
* Removed empty optional toggle_tickets annotations.
* Removed deprecated toggle_category, toggle_status,
and toggle_expiration_date annotations.
* Fixed some indents, use cases, and implementations.

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.
This allows course staff to add arbitrary HTML to the sidebar on the About page.
A waffle switch has been added in the course_experience app to allow enabling and disabling of this feature.
