MGNLCE-85 for details.
The remaining work consists the following steps
- copy & paste the solution from ce (yes sounds stupid but this was already the case before with cargo. We should resolve that soon but thats not part of the dockerization effort) (see branch)
- adapt tests (mostly the pure integration tests) to use the new DIRECT_AUTHOR, DIRECT_PUBLIC URLs where appropriate (partially done for integration tests)
- fix failing ui-tests (see sub-tasks)
