Describe the bug
Grader Service always spawns the same image at startup. The behavior is controlled in a very convoluted way:
if we set the value of the resolveImageName to none in the grade-service chart, then a default value is loaded. We're supposedly injecting the value as config at runtime, but it's not clear if we have a reference for this on any remote branch
The following series of commits shows a number of approaches that were tried during the initial process of finding a solution:

04f9d44d72841a7fd5c853a1b04a08c51dca98e1
If I understand correctly, the callable resolveImageName should be defined in such a way that it is able form a request to the lecture config server that contains a valid lecture ID of the config to be loaded. The image name and tag are part of the config, so this is how we would determine what image kubespawner uses. The definition of this function gets passed in by the values file grader_service_config.yaml, but it seems like we do not have a current reference of a working definition on a remote branch, see the relevant gitlab issue
It did seem at one point like @florian-jaeger got this working, although I could be misremembering this.
In any case, we need a solution for this issue by next week, as the functionality is of primary importance.
