* feat: Adds a new discussion topic configuration mechanism
The new discussion configuration system links discussion topics directly to the course structure. This change adds a new task that sends a discussion update signal if there are any changes to the course. This signal includes all the context needed to update the configuration of the course.
The handler for this new event will create a new entry for each unit that needs a topic in the database. In the future this will be used to see the topics in the course.
* fix: add support for marking a provider as supporting LTI
* fix: review feedback
