Add a new flag -with_ranger in testdata/bin/run-hive-server.sh to start Hive with Ranger integration. The relative configuration files are generated in bin/create-test-configuration.sh using a new varient ranger_auth in hive-site.xml.py. Only Hive3 is supported. Current limitation: Can't use different username in Beeline by the -n option. "select current_user()" keeps returning my username, while "select logged_in_user()" can return the username given by -n option but it's not used in authorization. Tests: - Ran bin/create-test-configuration.sh and verified the generated hive-site_ranger_auth.xml contains Ranger configurations. - Ran testdata/bin/run-hive-server.sh -with_ranger. Verified column masking and row filtering policies took effect in Beeline. - Added test in test_ranger.py for this mode.
