The current logic for showing discussion providers makes it hard to switch
from the legacy to the new provider. This commit changes the conditions in
which different providers are shown, and which provider is used as default.
Before this commit, the new provider would be hidden if the legacy provider
was in use and vice-versa. So both would only be shown if neither legacy
nor the new provider were in use (i.e. an LTI provider was in use).
Now, all providers are always displayed to global staff. If the waffle
flag for the new provider is set
(`discussions.enable_new_structure_discussions`), then new provider is
always displayed, and the legacy provider is hidden unless it's currently
in use.
If flag is not set, then the new provider is always hidden unless it is
used by a course.
Finally, the default provider now depends on the flag above. If it is
set globally, then the default provider is the new provider, otherwise
the legacy provider remains the default provider.
* feat: Adds discussions settings for new discusions experience
This commit adds new discussions settings for the new discussions experience. These are stored in the course so they can be a part of course import/export flow.
These are also added to the discussions configuraiton API to allow MFEs to update the settings.
The discussions API is currently available via LMS, however that means it cannot save changes to the modulestore. This also adds the API to the studio config so it can now also be accessed from studio and be used to save course settings.

For authenticated users that are not global staff, changing discussion
providers after a course has started fails with 403 Forbidden.

BREAKING CHANGE:
Course staff, who were previously allowed to do this operation,
will instead receive a 403 Forbidden response.
* feat: Course Apps API
This adds a new concept called course apps. These are exposed via a new
"openedx.course_app" entrypoint, which helps the LMS and studio discover such
apps and list them in a new rest api for the same.
These course apps will drive the pages and resources view in the course authoring
MFE. This system will track which apps are enabled and which are disabled. It
also allows third-party apps to be listed here by using the plugin entrypoint.
* Apply feedback from review
Else, we risk updating it when we don't intend to, eg:
- changing from an LTI-backed provider (Piazza) to a non-LTI-backed
provider (legacy)
- the settings are no longer relevant
- changing from a non-LTI-backed provider (legacy) to an LTI-backed
provider (Piazza)
- the settings _are_ now relevant
This commit adjusts a few values in our discussions configuration APIs to make them match what the frontend needs, as well as to more accurately reflect the providers available today.
- The `active` provider ID is expressed as None if it doesn’t exist
- The “cs_comments_service” provider has been renamed “legacy” - when we implement the new discussions micro-frontend, we’ll also have a separate provider for that, so they can’t both be “cs_comments_service”. Also, cs_comments_service is such a bad name for anything.
- The hard-coded providers list in get_supported_providers now includes ‘legacy’ and ‘piazza’, our two known providers. This list will be updated as more known providers come online.
- The PROVIDER_FEATURE_MAP has similarly been updated.
