Broker Load to support JSON loading from S3

[alberttwong]

The only alternative is JSON Stream Load using HTTP.

@alberttwong Is there a real need to load JSON data using Broker Load? from HDFS or S3?

I think it's reasonable. Many users would like to use S3 as universal data exchanger, which should also include JSON files.
