Merge #16978: test: Seed test RNG context for each test case, print seed

fae43a97ca test: Seed test RNG context for each test case, print seed (MarcoFalke)

Pull request description:

  Debugging failing unit tests is hard if the failure is non-deterministic and the seed is not known.

  Fix that by printing the seed and making it possible to set the seed from outside.
