Description

  From my side, it is necessary to set my custom `StreamOperatorFactory` when I ’m calling  `ConnectedStreams`#transform so that I can set up my own `OperatorCoordinator`. 

 Well, currently, `ConnectStreams` seems not to give the access, the default behavior is using `SimpleOperatorFactory`.  After checking the code, I think it is a trivial change to support that. If no one is working on it, I'm willing to doing that.  : )
