Ray Ingles resolved GEODE-9495.

       Resolution: Fixed

Dynamically checks the TIME_WAIT value (which determines how long sockets are held after closing) for Linux and OSX to minimize sleep time.

> GEODE-9338 includes the addition of a Thread.sleep(240000) in the class cleanup. This wait is necessary to allow the sockets used in this class to exit the TIME_WAIT state. Out of Mac, Linux, and Windows, Windows has the longest default TIME_WAIT, which is 240 seconds. So currently at the end of the PubSubNativeRedisAcceptanceTest tests, we wait for 240 seconds.
> Another solution was proposed that involved parsing netstat outputs to find out when enough sockets have been freed, but the complexity didn't buy us much there.
> A potential other solution would be to reduce the TIME_WAIT period when running the tests in CI. 
> If we don't wait for the TIME_WAIT period to be up then other tests being run after it will get bind exceptions.
