......................................................................

IMPALA-10921 Add script to compare TPCDS runs.

This script compares 2 runs of TPCDS by parsing their respective
Impala plain text query profiles. It currently outputs the peak
memory comparision of both runs where:
1. It compares average per-node peak memory and geo-mean
   per-node peak memory.
2. It compares max peak memory reduction among Hash operators.

It can be extended to other comparisions in future.

Example usage:

 tpcds_run_comparator.py <path to base run profile> <path to new run profile>
 <path to result csv file>
