What's changed

1. Containers entrypoint for cms-worker and lms-worker from:

["celery", "worker", "--app=cms.celery", "--loglevel=info", "--hostname=edx.cms.core.default.%%h", "--maxtasksperchild", "100", "--exclude-queues=edx.lms.core.default"]
["celery", "worker", "--app=lms.celery", "--loglevel=info", "--hostname=edx.lms.core.default.%%h", "--maxtasksperchild=100", "--exclude-queues=edx.cms.core.default"]

To:

["celery", "--app=cms.celery", "worker", "--loglevel=info", "--hostname=edx.cms.core.default.%%h", "--max-tasks-per-child", "100", "--exclude-queues=edx.lms.core.default"]
["celery", "--app=lms.celery", "worker", "--loglevel=info", "--hostname=edx.lms.core.default.%%h", "--max-tasks-per-child=100", "--exclude-queues=edx.cms.core.default"]

2. apps/openedx/config/partials/auth.yml doesn't have CONTENTSTORE: null

3. mongob parameters changed replicaSet to None

   mongodb_parameters = {
        "password": None,
        {% endif %}
        "db": "{{ MONGODB_DATABASE }}",
   +    "replicaSet": None,
    }

4. It was added to openedx/config.settings/partials/common_lms.py:

   +BULK_EMAIL_SEND_USING_EDX_ACE = True
   +
   +# Make it possible to hide courses by default from the studio
   +SEARCH_SKIP_SHOW_IN_CATALOG_FILTERING = False

How to test

1. Use this branch MJG/tutor-14
2. Use the manifests-a-j-goddard branch MJG/nutmeg-installation (I know it's nuez)
3. Generate manifests using the reference. Notice we're using template_root: "tutor14"
