What changes were proposed in this pull request?

Add DESCRIBE FORMATTED statements for every TPC-DS table and column

Why are the changes needed?

  1. Ensure TPC-DS dump does not lose information upon upgrade
  2. Extra code coverage for DESCRIBE statement with real metadata at big scale

Does this PR introduce any user-facing change?

No

How was this patch tested?

mvn test -Dtest=TestTezTPCDS30TBPerfCliDriver

The new tests increase the running time of the suite from 250.8s to 292.3s (~40 seconds) on my local environment.
