BREAKING: get rid of the LegacyWaffle-based CourseWaffleFlag.
Both CourseWaffleFlag and FutureCourseWaffleFlag now use the modern
WaffleFlag as parent class. FutureCourseWaffleFlag left to support ORA
transition to modern waffle.
Switch to the ORA version which supporting new Waffles.
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.
The only way to access the legacy courseware is now through the
Studio preview feature (and at some point, when the MFE supports a
preview mode, we can then remove even that).
This drops the courseware.use_legacy_frontend waffle.
This was the "outline tab" view of the course. Preceded by the
course info view, succeeded by the MFE outline tab.
In addition to the course home view itself, this drops related
features:
- Legacy version of Course Goals (MFE has a newer implementation)
- Course home in-course search (MFE has no search)
The old course info view and course about views survive for now.
This also drops a few now-unused feature toggles:
- course_experience.latest_update
- course_experience.show_upgrade_msg_on_course_home
- course_experience.upgrade_deadline_message
- course_home.course_home_use_legacy_frontend
With this change, just the progress and courseware tabs are still
supported in legacy form, if you opt-in with waffle flags. The
outline and dates tabs are offered only by the MFE.

For the dates courseware tab, we no longer respect the
course_home_use_legacy_frontend waffle flag that enabled the
legacy version in Maple.
Instead, we always send the user to the MFE.
MFEs will be required for the Nutmeg release. This dates tab is
the first to fall, but others will follow.

Change has_access to deny 'load' support for Old Mongo courses.
This is in service of dropping support for these ancient
courses and removing legacy code that they rely on.
DEPR-58
Deprecates the following attributes from ModuleSystem:
* replace_urls
* replace_course_urls
* replace_jump_to_id_urls
A new ReplaceURLService is created as replacement with a unified replace_urls method
Description
This is a follow up to #29058 and #29413. This is the next step in moving part of the modulestore data (the course indexes / "active versions" table) from MongoDB to MySQL.
There are four steps planned in moving course index data to MySQL:
Step 1: create the tables in MySQL, start writing to MySQL + MongoDB ✅ done
Step 2: migrate all remaining courses to MySQL ✅ done
Step 3: switch reads from MongoDB to MySQL (this PR)
Step 4 (much later, once we know this is working well): stop writing to MongoDB altogether.
Supporting information
OpenCraft Jira ticket: MNG-2557
Status
✅ Tested with a large Open edX instance is in progress.
Testing instructions
Try making changes in Studio and verify that they work fine.

Convert more tests from MONGO_AMNESTY to SPLIT modulestores.
This is in preparation for just wholesale denying access to Old
Mongo, so I either converted tests to split or just deleted some
test variants that were Old Mongo specific. (e.g. ddt lines)
It's long past time that the default test modulestore was Split,
instead of Old Mongo. This commit switches the default store and
fixes some tests that now fail:
- Tests that didn't expect MFE to be enabled (because we don't
enable MFE for Old Mongo) - opt out of MFE for those
- Tests that hardcoded old key string formats
- Lots of other random little differences
In many places, I didn't spend much time trying to figure out how to
properly fix the test, and instead just set the modulestore to Old
Mongo.
For those tests that I didn't spend time investigating, I've set
the modulestore to TEST_DATA_MONGO_AMNESTY_MODULESTORE - search for
that string to find further work.
If a learner changes modes (like upgrades to a verified learner),
we will reset their schedule for them. But if they did this before
the course started, we would accidentally set their schedule to
the current time. So when the course did start, they would already
appear to be behind schedule.
That's silly. So now we always look at course start time when
resetting the learner's schedule.

Non-enrolled staff users were being shown enroll links for courses
that you can't self-enroll for (masters-only, invitation-only, etc).
This fixes the outline page to ignore staff status for that check.

Split modulestore persists data in three MongoDB "collections": course_index (list of courses and the current version of each), structure (outline of the courses, and some XBlock fields), and definition (other XBlock fields). While "structure" and "definition" data can get very large, which is one of the reasons MongoDB was chosen for modulestore, the course index data is very small.
By moving course index data to MySQL / a django model, we get these advantages:
* Full history of changes to the course index data is now preserved
* Includes a django admin view to inspect the list of courses and libraries
* It's much easier to "reset" a corrupted course to a known working state, by using the simple-history revert tools from the django admin.
* The remaining MongoDB collections (structure and definition) are essentially just used as key-value stores of large JSON data structures. This paves the way for future changes that allow migrating courses one at a time from MongoDB to S3, and thus eliminating any use of MongoDB by split modulestore, simplifying the stack.
