> Now that we have TezUserPayload being used internally to represent user 
> payload it may be useful to make it user facing on the API for specifying 
> payloads. Advantages
> 1) Clear code for the user instead of having untyped byte[] everywhere
> 2) Lets us internally evolve the representation of user payload and make it 
> more efficient without having to break APIs. We can start with 
> TezUserPayload(byte[]) and then move on to TezUserPayload(ByteBuffer) and so 
> on while maintaining backwards compatibility without needing to add new 
> methods. Old code can be translated within TezUserPayload while user migrates 
> the code.
