    [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.
