The generated data is identical to the pregenerated tpch.tar.gz and tpcds.tar.gz data that was used previously and were not publically accessible. This adds a "preload" hook to bin/load-data.py that can execute custom logic for each data set. This is used to call the TPC-H and TPC-DS data generation utilities that are already available in the Impala toolchain. Testing: Ran private test job with loading from snapshot disabled and without the tpch/tpcds tarballs available.
