[SPARK-18161] [Python] Allow use of pickle to serialize > 4 GB objects where available ## What changes were proposed in this pull request? Since pickle protocol 4 (available in Python 3.4+) allows for serialization of > 4 GB errors, use pickle protocol 4 when available in the Broadcast and PickleSerializer classes. ## How was this patch tested? This was tested through pyspark shell and serializing a large numpy array with / without the changes.
