IMPALA-8400: Implement Ranger audit event handler

This patch implements Ranger audit event handler to behave similarly to
the Hive/Ranger audit event handler, most notably:
- Buffer the audit events during authorization and only flush them once
  the authorization is complete.
- The audit will only add the event for the first failure.
- Create an audit event handler per statement.

Testing:
- Added test cases in RangerAuditLogTest
- Ran FE tests
- Ran all E2E authorization tests
