IMPALA-8530: Return more user friendly error messages on unsupported SQL
This patch updates the error messages to return more friendly error
messages for the unsupported SQL statements when running with Sentry or
Ranger to improve user experience. This patch tries to differentiate
between UnsupportedOperationException, which is an internal exception to
indicate a programming error vs UnsupportedFeatureException, which is
an exception that will be exposed to the users to indicate that a
feature is not supported.
Testing:
- Added tests for unsupported SQL
- Ran FE tests
- Ran E2E authorization tests
