Bring back certain removed POSTS

[hamrt]

Currently all post actions have been removed. I would like to propose POST options that facilitate the following use cases:

• The ability for students to enroll in a course
• The ability for students to add a photograph of themselves
• The ability for students to use the schedules to add their own data or at least combine the schedule data generated by the OO-API with their own calendars.

OK, lets discuss this in the next meetup!

Is part of the 'notifications' architecture -> there is a proposal in there how a post and how a delete should work.

Need additional use cases

Close for now wait until the questions for POST requests are more specific
