fa69588537 test: Make PORT_MIN in test runner configurable (MarcoFalke)

Pull request description:

  This is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:

  * We spin up several nodes per test (each node gets its own port)
  * We run several tests in parallel

  So to avoid nodes from different tests colliding on ports, the port assignment must be deterministic (can not be dynamic).

  Fixes: #10869
