> Affects Versions: 0.18.0

> A few bugs in ScriptBasedTopology:
> 1) topology.script.number.args is not validated; if this is <= 0, the runResolveCommand() method will run its outer loop an infinite number of times.
> 2) CachedDNSToSwitchMapping assumes that if a List is returned, it has the same cardinality as the number of names. ScriptBasedMapping should return 'null' instead of a mis-sized list on error
