Description

Current incremental policy update mechanism may cause issues in two cases.

      1. When policy is updated, it is consist of two operations: delete then add. Policy is temporarily unavailable after delete operation and before add operation. It may cause task failure.

      2. RangerResourceTrie is also updated when matching policies (ref RANGER-2760 and RANGER-2761). Without read write lock, it will lead to chaos and inaccurate result.
