Feature/#25 open api

Feature

Summary

This MR provides an OpenAPI documentation for the API at ahikar/openapi/index.html.

❗ Important

I'm not sure where the Apache config is. ahikar/openapi/index.html should be exposed to https://ahikar-dev.uni-goettingen.de/openapi (or somewhere else if you have an alternative).

Does the result of the MR comply to our "definition of done"?

• I don't know
