IMPALA-7398: Add logged_in_user alias for effective_user

This patch adds an alias to the effective_user function so that
views created in Hive using the logged_in_user function will work
in Impala.

Example:
CREATE VIEW foo.view1 AS SELECT * FROM foo.table1 WHERE
name=logged_in_user();

Tests:
- Added function and ran delegation tests
- Ran backend tests
- Ran custom-cluster tests including delegation

> When using sentry Hive will return a different value for 'current_user' than Impala.  This means a view using these values would be inconsistent between the two SQL engines.  By adding 'logged_in_user' as an alias for 'effective_user' views would be consistent between Hive and Impala.
