- Reference correct version of Django docs
- Updates to LMS envs diagram:
    - Rename aws.py reference in image (now production.py)
    - Remove deprecated and deleted environments
- Update note on `devstack_docker.py` to explain history

Background: I use private.py a lot in my devstack for my private configurations. But issues are raised when I need to change/override a setting that is defined in devstack_docker.py file. Since that file's contents are loaded after private.py, my private.py is useless against the settings in devstack_docker.py.

Description: Now that the devstack is dockerized, I think it makes more sense to import the private.py in the devstack_docker.py files i.e. at the end of configuration files hierarchy.

* Removing all settings that have OIDC in name

* Removing ENABLE_DOP_ADAPTER

* changes JWT_ISSUER value in devstack

The mako engine isn't able to find themed templates in devstack because
the path it checks is set before we enable comprehensive theming. This
Adds a settings section to  comment out if you want to enable
theming in devstack.

Add an LMS feature flag to enable courseware search for course staff
only. TNL-6931

Don't jam LOGIN_REDIRECT_WHITELIST into devstack_docker settings, we already define it in devstack (and we read private.py from devstack).

Created a data migration to add system wide student support
role, also registered SystemWideRoleAssignment into Django
admin.

LEARNER-4766

Fixes for new design as per instruction in this ticket.

LEARNER-3131

The LMS and edx-enterprise currently communicate via REST APIs, even
though they are all running within the same service.

Currently API URLs are constructed using LMS_ROOT_URL, but that is
problematic on some systems where the external LMS_ROOT_URL is not
accessible from the private network, or routing internal requests via
the external URL is not desireable.

This patch introduces a new setting variable LMS_INTERNAL_ROOT_URL which
defaults to the value of LMS_ROOT_URL for backwards compatibility.

The LMS and edx-enterprise will use LMS_INTERNAL_ROOT_URL to construct
API URLs instead of LMS_ROOT_URL.

This is a work in progress finished the 320px - 539px mobile
screen design.

LEARNER-2311

Moves ENABLE_ENTERPRISE_INTEGRATION to settings.FEATURES,
and changes the default value to False.

LEARNER-1115

This feature is not always needed and is not properly provisioned for devstacks.

Pulling URLs from settings allows us to rely on site configuration overrides in order to support multi-tenancy.

LEARNER-1103

This service is not currently available in Docker devstack.

This reverts commit 65f13dde.

This reverts commit 88dd85ca, reversing
changes made to bf8aef33.

This modifies the lang-pref django app to:
a) Use the current value of the 'edx-language-preference' cookie to set the
   users Accept-Language header on an incoming request.
b) At the end of the request, update the 'edx-language-preference' cookie
   to reflect the users current Language Preference choice, if any.

[LEARNER-542]

- Fixed LMS_ROOT_URL
- Fixed Enterprise API URL

These changes help simplify integrating with edx.org's separate marketing site.

ECOM-6627

This feature is not well-documented, so it is unclear how to setup Elasticsearch properly to make it work. The next person who needs to work on this feature will need to make it work and, ideally, document it.
