BREAKING CHANGE: Removes all code, tests, and settings related to indexing of V2 (blockstore-backed) content libraries in elasticsearch. This includes indexing of top-level library metadata as well as indexing of library block metadata. Operators who enabled the experimental Library Authoring MFE *and* the experimental ENABLE_CONTENT_LIBRARY_INDEX feature may notice that sorting, filtering, and searching of V2 libraries and their blocks may now be slower and/or less powerful. The ENABLE_CONTENT_LIBRARY_INDEX feature was already disabled by default, so most/all operators (including edx.org) should not notice any difference. Removed settings include: * FEATURES['ENABLE_CONTENT_LIBRARY_INDEX'] * ENABLE_ELASTICSEARCH_FOR_TESTS * TEST_ELASTICSEARCH_USE_SSL * TEST_ELASTICSEARCH_HOST * TEST_ELASTICSEARCH_PORT For rationale, see the updated "Status" section of: ./openedx/core/djangoapps/content_libraries/docs/decisions/0001-index-libraries-in-elasticsearch.rst
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://edx.readthedocs.io/projects/open-edx-building-and-running-a-course/en/latest/getting_started/CA_get_started_Studio.html#>`_
