[SPARK-3417] -Use new-style classes in PySpark

[mrocklin]

Tiny PR making SQLContext a new-style class. This allows various type logic to work more effectively

In [1]: import pyspark

In [2]: pyspark.sql.SQLContext.mro()
Out[2]: [pyspark.sql.SQLContext, object]

[JoshRosen]

Good catch! While you're at it, are there any other old-style classes in PySpark that should be made into new-style ones?

[JoshRosen]

Also, do you mind opening a JIRA ticket on https://issues.apache.org/jira/browse/SPARK and editing the title of your pull request to reference it, e.g. [SPARK-xxxx] Use new-style classes in PySpark?

[mrocklin]

Sure. Next time I find a few free minutes.

The title is a bit confusing, would you mind to change it to "Use new-style classes in PySpark" ?

The patch looks good to me, thanks!

(want to see how long it takes Jenkins to respond to me...)

[nchammas]

He's been pretty slow to respond lately. 10-15 min I'd say.

Looks like this only failed unrelated streaming tests (Exception encountered when attempting to run a suite with class name: org.apache.spark.streaming.kafka.KafkaStreamSuite) /cc @tdas.

I'm going to merge this to master.
