   Ah that's a very good point.
   
   Maybe we should not bother with ports at all but rather focus on hostnames. 
The set of resolvable hostnames should change a lot less than ports; a bogus 
hostname (that we can check for beforehand whether it resolves to anything) 
could be a better approach.
   This hostname could be awfully specific like 
"flink-qs-client-test-unavailable-host" so the chances of conflicts are 
basically 0.
