fa69588537bc91c0aedbc89ef1760d89cbffad75 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
