Lando API has a concept of "subsystems", each of which extend the `Subsystem` class -- a class containing various convenience methods to determine if a subsystem is initialized with the app context and configuration, whether it is ready or not, whether it is healthy or not, and a mechanism for ensuring that the subsystem is ready.

This subsystem structure is tied to the Flask app and must be adapted to Django. Some subsystems may need to be dropped altogether (e.g., `lando_ui_subsystem`) or re-implemented in a different way. This is a preliminary list:
- logging_subsystem                                                                                                                                                                                                  
- sentry_subsystem
- auth0_subsystem
- cache_subsystem
- celery_subsystem
- db_subsystem
- lando_ui_subsystem
