TPC-DS test results

We need to run TPC-DS tests with scale factor 1000 (1Tb).

Results should be provided as a spreadsheet with versions(11.4 and 10.6) comparing.

Results from the tests of the TPS-DS queries should be compared with expected ones.

We should run each query two times.
Results should be grouped for every 10 queries.

Because data generation and uploading to a db may take a lot of time, we save the created db and reuse it every time. It may save us a lot of time.
