---------------------------------

Thanks [~colin_mjj] and [~lskuff] for your review. I updated the patch again with a more advanced
"CASCADE" option. Please take a look!

> We've seen ORA-0955 duplicate name issue while running Sentry upgrade scripts.
> Running Oracle 11g. We eventually tracked it to /opt/cloudera/parcels/CDH/lib/sentry/scripts/sentrystore/upgrade/004-SENTRY-74.oracle.sql:
> {code:sql}
> ALTER TABLE SENTRY_DB_PRIVILEGE DROP CONSTRAINT "SENTRY_DB_PRIV_PRIV_NAME_UNIQ";
> ALTER TABLE SENTRY_DB_PRIVILEGE ADD CONSTRAINT "SENTRY_DB_PRIV_PRIV_NAME_UNIQ" UNIQUE
("SERVER_NAME","DB_NAME","TABLE_NAME","COLUMN_NAME","URI","ACTION","WITH_GRANT_OPTION");
> {code}
> Although constraint was dropped, it fails to re-add, as there was an implicit index added
with same name as well (expected behavior according to docs: http://docs.oracle.com/cd/B19306_01/server.102/b14200/clauses002.htm
See: "Unique Constraints").
> Dropping the index allowed us to finish upgrading the schema successfully.
