This is trying to tune the integration tests for speed and stability.
Instead of default ports, it will detect free ports on the system to bind to for memberlist and http.
It also reduces a few memberlist time duration to ensure there is a quick convergence.Update: I am ignoring memberlist all together in favour of the inmemory kv, which improves the test runtime by quite a bit.
