This patch adds a startup flag so that by default the catalog server will not consolidate the grant/revoke requests sent to the Ranger server when there are multiple columns involved in the GRANT/REVOKE statement. Testing: - Added 2 end-to-end tests to make sure the grant/revoke requests sent to the Ranger server would be consolidated only when the flag is explicitly added when we start the catalog server.
