Fix Kafka spout to maintain backward compatibility
[STORM-1499] Fix Kafka spout to maintain backward compatibility

STORM-1220 introduced some changes where in one place it passes ByteBuffer as is instead of byte[].
Existing bolts (0.10.0) expects a byte[] and fails with
"java.lang.RuntimeException: java.lang.ClassCastException: java.nio.HeapByteBuffer cannot be cast to [B "
This patch addresses the issue by emiting byte[] instead of ByteBuffer.
