IMPALA-7795: Implement REFRESH AUTHORIZATION statement
This patch implements REFRESH AUTHORIZATION statement to explicitly
refresh authorization metadata. This statement is useful to force
Impala to refresh its authorization metadata when there is an external
update to authorization metadata without having to wait for the Sentry
polling or call INVALIDATE METADATA. Some tests were updated to use
REFRESH AUTHORIZATION instead of INVALIDATE METADATA to make the tests
run faster.
Syntax:
REFRESH AUTHORIZATION (authorization must be enabled to execute this
statement)
Testing:
- Added new FE tests
- Added new E2E authorization tests
- Ran all FE tests
- Ran all E2E authorization tests

> There is currently no way to refresh authorization data (privileges and principals) without calling "invalidate metadata" (which is very costly) and increasing the polling time. There needs to be a way to explicitly refresh the authorization data similar to "refresh functions".
