In order to remove the deprecated flag_undefined_default=True argument, this commit updates the following flags to always be enabled using a new temporary class: - course_experience.course_outline_page - course_experience.unified_course_tab Adds a temporary setting `USE_DEFAULT_TRUE_NAMESPACE`, to enable a monitored rollout of this change. TNL-7061 is the ticket where these flags will actually be removed. This requires more careful work including removing all dead code, and potentially refactoring tests that were testing shared functionality, but only when the flag was False. ARCHBOM-1316
Open EdX Features ----------------- This is the root package for Open edX features that extend the edX platform. The intention is that these features would ideally live in an external repository, but for now they live in edx-platform but are cleanly modularized.
