As a teacher
I want to be able to delete an activity in the course index
so I can clean the content up

As per current behavior, deleting a section deletes from the database:

• The module itself
• Information about module completion.
• Information about module availability.
• Module tags.
• Specific information per plugin.
• Doesn’t check deleted activity was part of “availability requirements” of any other module.

(forget about the rest of the options for now)

Prototype: https://www.figma.com/proto/OfCvqK069Oz6Fvqq2xcZWI/Create-a-course?node-id=3285%3A38308&scaling=scale-down

Acceptance criteria:

1. User needs permissions to delete activities.
2. User needs to confirm the action.
3. The activity will be removed in the course index and course main content.
4. Some activity types would require asynchronous deletion. We will keep current behavior in those cases.

Technical tasks:

• Add cm_delete state action
