> 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.
