hive-sre (beta version 3)

Prototype Release for u3e (u3 execute) process. See: https://github.com/cloudera-labs/hive-sre/blob/sre_3/u3e.md

This is a beta release that applies only to MySql/MariaDB backed metastores (at this time). If will 'directly' apply the needed updates to the metastore DB without having to run the HiveSQL statements generated by u3.

This should only be run on metastores 'immediately' before or right after the upgrade to CDP (Hive 3).

If you want to test in lower environments, make a copy of the metastore DB and reference it in the config OR backup, run, and restore the db in older environments.

This process will run in seconds or minutes, compared to hours(days) needed to run LARGE conversions.
