Issue XD-2512: Byte[] to String conversion should support application/json 
See http://stackoverflow.com/questions/27491237/spring-xd-tcp-source-outputs-byte-array-instead-of-string-how-to-output-regu. Same behavior as --outputType text/plain but more intuitive to use application/json if the stream author expects the source to emit json. No content validation will be done.
