Context:
As discussed in https://github.com/camunda/camunda-optimize/pull/2587#discussion_r484761236 we want to setup a nightly fuzzy import mediator permutation test that takes 8 process instance relevant mediators and verifies all potential permutations result in the same expected state of a process instance.

AT:

• nightly test job verifies all permutations of 8 randomly picked processInstance relevant import mediators (8! makes 40k combinations every night)
