Depends on https://github.com/mitodl/hq/issues/10405

Closes https://github.com/mitodl/hq/issues/10416

Description (What does it do?)

• Refactors the MITx Online to ingest certain programs as courses
• Adds a "Program as Course" resource tag to these resources.
• Puts it behind a feature flag because the product page for a program->course likely won't work right yet (until https://github.com/mitodl/hq/issues/10429 is implemented)

How can this be tested?

• Log in to posthog and verify that the progam-to-course feature flag for the MITLearn-RC project is currently rolled out to 0% of users
• Set these env values in your backend.local.env file:

  MITX_ONLINE_BASE_URL=https://rc.mitxonline.mit.edu/
  MITX_ONLINE_COURSES_API_URL=https://rc.mitxonline.mit.edu/api/v2/courses/
  MITX_ONLINE_PROGRAMS_API_URL=https://rc.mitxonline.mit.edu/api/v2/programs/
  

• Set these to the same as RC in your shared.local.env file:

  POSTHOG_API_HOST=https://ph.ol.mit.edu
  POSTHOG_PERSONAL_API_KEY=
  POSTHOG_PROJECT_API_KEY=
  POSTHOG_PROJECT_ID=
  POSTHOG_ENABLED=True
  

• Run docker compose run --rm web python manage.py backpopulate_mitxonline_data
• Search for "Fundamentals of Deep Learning" - it should be returned as a program
• Log back in to posthog and edit the prorgam-to-course feature flag so that it is rolled out to 100% of users
• Wait a few minutes, then run the backpopulate again.
• Redo the search, this time it should show up as a course. Open the drawer for the course, that should still work.
• Set the feature flag back to 0% of users in posthog.
