[FLINK-2609] [streaming] auto-register types This PR attempts to register all streaming operator output types at kryo. In contrast to the Batch API * the registration is done when an operation is defined, opposed to after all operations are defined * autoRegistration must be disabled before an operation is created to have an effect * the deduplicator HashSet is a protected field of the DataStream class opposed to a local variable * still not visible to users * accessible by all DataStream's * accessible by Non-DataStream streams (KeyedStream etc) as long as they are in the same package * a separate superclass for all Streams is a good idea in the long run Most operations use DataStream#transform(), as such most registrations will take place here. One exception are key-selectors, which aremysteriously hidden in the Keyed-/Joined-/CoGroupedStreams where()/equalTo() methods, where their registration takes place.
