Issue XD-2599: Create a BroadcasterMessageHandler that uses a 'Serialized' Broadcaster
This is a parallel implementation to the RxJava https://github.com/spring-projects/spring-xd/blob/master/spring-xd-rxjava/src/main/java/org/springframework/xd/rxjava/SubjectMessageHandler.java That will allow multiple threads to broadcast an event but allow processing to occur one at a time on any thread.
