    We need to find a solution for the webfrontend, though. Starting it on random ports is
not a real solution. Also the user that wants to see progress needs to connect manually to
the web server of the leader JobManager.

> Having standby JM instances for job manager high availabilty requires distributed coordination
between JM, TM, and clients. For this, we will use ZooKeeper (ZK).
> Pros:
> - Proven solution (other projects use it for this as well)
> - Apache TLP with large community, docs, and library with required "recipies" like leader
election (see below)
