📝 [open-zaak/open-zaak#1649] Document envvars

replace the manual envvar docs with OAf `generate_envvar_docs`, this ensure that generic envvars that are used by every component are documented centrally in OAF and custom envvars can be documented in the code where they are declared

-* ``SUBPATH``: If hosted on a subpath, provide the value here. If you provide
-  ``/gateway``, the component assumes its running at the base URL:
-  ``https://somedomain/gateway/``. Defaults to an empty string.
 
-* ``SENTRY_DSN``: URL of the sentry project to send error reports to. Defaults
-  to an empty string (ie. no monitoring).
+Optional

+* ``USE_X_FORWARDED_HOST``: whether to grab the domain/host from the X-Forwarded-Host header or not. This header is typically set by reverse proxies (such as nginx, traefik, Apache...).

+* ``IS_HTTPS``: Used to construct absolute URLs and controls a variety of security settings. Defaults to the inverse of ``DEBUG``.
+* ``CACHE_DEFAULT``: redis cache address for the default cache. Defaults to: ``localhost:6379/0``.

+* ``EMAIL_HOST_PASSWORD``: password to connect to the mail server. Defaults to: ``(empty string)``.
+* ``EMAIL_USE_TLS``: whether to use TLS or not to connect to the mail server. Should be True if you're changing the ``EMAIL_PORT`` to 487. Defaults to: ``False``.

+* ``LOG_REQUESTS``: enable logging of the outgoing requests. Defaults to: ``False``.
+* ``ENVIRONMENT``: An identifier for the environment, displayed in the admin depending on the settings module used and included in the error monitoring (see ``SENTRY_DSN``). The default is set according to ``DJANGO_SETTINGS_MODULE``.
+* ``SUBPATH``: If hosted on a subpath, provide the value here. If you provide ``/gateway``, the component assumes its running at the base URL: ``https://somedomain/gateway/``. Defaults to an empty string. Defaults to: ``None``.
+* ``RELEASE``: The version number or commit hash of the application (this is also sent to Sentry).
+* ``NUM_PROXIES``: the number of reverse proxies in front of the application, as an integer. This is used to determine the actual client IP adres. On Kubernetes with an ingress you typically want to set this to 2. Defaults to: ``1``.
+* ``CSRF_TRUSTED_ORIGINS``: A list of trusted origins for unsafe requests (e.g. POST). Defaults to: ``[]``.
+* ``NOTIFICATIONS_DISABLED``: indicates whether or not notifications should be sent to the Notificaties API for operations on the API endpoints. Defaults to ``True`` for the ``dev`` environment, otherwise defaults to ``False``.

-  header or not. This header is typically set by reverse proxies (such as nginx,
-  traefik, Apache...). Default ``False`` - this is a header that can be spoofed and you
-  need to ensure you control it before enabling this.
 
-* ``DISABLE_2FA``: whether to disable two-factor authentication. Defaults to ``False``.

-* ``LOG_REQUESTS``: whether to enable logging of outgoing HTTP requests. Defaults to ``False``.
 
-* ``LOG_OUTGOING_REQUESTS_DB_SAVE``: whether to save logged requests to the database. Defaults to ``False``.

+Initial superuser creation (Docker only)
+----------------------------------------
+
+A clean installation of Objects API comes without pre-installed or pre-configured admin
+user by default.
+
+Users of Objects API can opt-in to provision an initial superuser via environment
+variables. The user will only be created if it doesn't exist yet.
+
+* ``OBJECTS_SUPERUSER_USERNAME``: specify the username of the superuser to create. Setting
+  this to a non-empty value will enable the creation of the superuser. Default empty.
+* ``OBJECTS_SUPERUSER_EMAIL``: specify the e-mail address to configure for the superuser.
+  Defaults to `admin@admin.org`. Only has an effect if ``OBJECTS_SUPERUSER_USERNAME`` is set.
+* ``OBJECTS_SUPERUSER_PASSWORD``: specify the password for the superuser. Default empty,
+  which means the superuser will be created _without_ password. Only has an effect
+  if ``OBJECTS_SUPERUSER_USERNAME`` is set.
