Dominik Richter c6f896cad3 run full docker test in parallel
With just one more issue left: the formatter is going to report multiple time, including spitting out errors multiple times. Also need to remove some of the custom formatting around the current state of containers.

As a bonus: This further improved testing speed (30% on the current environment) and will allow us to grow the supported platforms for tests easily.
