Review request for sentry, Arjun Mishra, Haley Reeve, and kalyan kumar 
kalvagadda.


Bugs: sentry-2501
    https://issues.apache.org/jira/browse/sentry-2501


Repository: sentry


Description
-------

The filter in SentryMetaStoreFilterHook does not cache sentry privileges. 
Therefore, for each item in the list, sentry client has to get privileges from 
sentry server.

To improve performance, we need to add cache in SentryMetaStoreFilterHook
