Rewrite to use FastAPI instead (#13)

* Rewrite to use FastAPI instead

Also prepare the ETOS API to become the main API of ETOS.

* Added a new test and cleanup grapqhl client

New test for testing that the redirection works.
A new utilities module for the ETOS endpoint.
Wait for artifactCreated instead of just sending a single request
Move artifact specific code from the graphql client to utilities.

* Fix a time sleep bug
