[SPARK-8337][Streaming][Pyspark] Add MessageHandler for Kafka Python API
Propose a way to add messageHandler for Kafka Python API, offer user a
similar pattern to use message like Scala/Java:
```python
def getOffset(m):
return m and m.offset
KafkaUtils.createDirectStream(ssc, topic, kafkaParams,
messageHandler=getOffset)
```
Internally serialize the Kafka `MessageAndMetadata` to Python using Pickler.
Please help to review, thanks a lot.
