* feat: store content.child_usage_keys in Container search document Stores the draft children + published children (if applicable) Related fixes: * fix: lib_api.get_container does not take a "user" arg * refactor: fetch_customizable_fields_from_container does not need a "user" arg * refactor: moves tags_count into LibraryItem because anything that appears in a library may be tagged. * refactor: remove get_container_from_key from public API API users must use get_container and ContainerMetadata. * refactor: made set_library_item_collections take an entity_key string instead of a PublishableEntity instance, so we don't need to fetch a Container object to call it. * refactor: changed ContainerLink.update_or_create to take the container PK instead of a Container object, since this is enough. Added container_pk to ContainerMetadata to support this.
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>`_
