I'm not entirely sure, but I think we cannot put the `JobsOverviewHandler`
under `/jobs/overview`. The problem is that it collides with `/jobs/:jobid`. If
I access `http://localhost:8081/jobs/overview` I get a
`java.lang.IllegalArgumentException: contains illegal character for hexBinary:
overview`. Not sure why it works when the call comes from the web ui.
So either we don't do this change or we register the handler under `/jobs`.
Then we would simply return a detailed view when accessing jobs. In the future
we could add an optional filter statement to not include all information. What
do you think @zentol?
