I concur with @jerryshao completely. If the only purpose of this patch is
to create multiple input streams and union them together, its just easy to do
it manually.
`ssc.union((1 to numConsumers).map(_ => KafkaUtils.createStream(....))`
Rather if there was any smart allocation of topics to streams that did
intelligent load balancing etc, then it is worth wrapping that complex
functionality into a separate API call.
