Review request for ranger.


Repository: ranger


Description
-------

Modifying roles should not affect the update of the policy version. After 
removing this code, apart from not impacting the original authorization and 
authentication, what's important is that the impact of this code on performance 
has been verified in the production environment: After modifying the roles 
dozens of times, after a certain period, the P50 of the client's policy 
retrieval has decreased from dozens of seconds to the millisecond level.

Testing
-------

Tested the policies and roles for full and incremental data retrieval using the 
Spark SQL engine, and the permissions all took effect normally.


Thanks,
