Both 'provider' and 'provider_type' have been used for storing the discussion provider type in course 'discussions_settings' field, there are some places in the code checking for 'provider' and others checking for 'provider_type', in some cases this can cause a bug where it doesn't detect the correct provider which causes discussion settings not being copied correctly when a course is cloned. This change prioritises the `provider_type` setting over `provider` and reads `provider` only as a fallback. The `provider` setting is now made read-only just for backwards-compatibility, to avoid confusion.
CMS
===
This directory contains code relating to the Open edX Content Management System ("CMS"). It allows learning content to be created, edited, versioned, and eventually published to the `Open edX Learning Mangement System <../lms>`_ ("LMS"). The main user-facing application that CMS powers is the `Open edX Studio <https://docs.openedx.org/en/latest/educators/concepts/open_edx_platform/what_is_studio.html>`_
