[SPARK-7788] Made KinesisReceiver.onStart() non-blocking
KinesisReceiver calls worker.run() which is a blocking call (while loop) as
per source code of kinesis-client library -
https://github.com/awslabs/amazon-kinesis-client/blob/v1.2.1/src/main/java/com/amazonaws/services/kinesis/clientlibrary/lib/worker/Worker.java.
This results in infinite loop while calling
sparkStreamingContext.stop(stopSparkContext = false, stopGracefully = true)
perhaps because ReceiverTracker is never able to register the receiver (it's
receiverInfo field is a empty map) causing it to be stuck in infinite loop
while waiting for running flag to be set to false.
