> It would be useful to add an API to Sentry Service that allows Sentry Service clients
to read the service's configuration values. The Hive Metastore has a similar API:
> "String getConfigValue(String propertyName, String defaultValue)"
> One specific use case for Sentry is to make it possible for clients that cache policy
metadata (e.g. Impala) to read the admin group(s) so they can also cache this information
and authorize GRANT/REVOKE requests without making an RPC to the Sentry service. The client
could periodically refresh the configuration information to ensure it is up to date.
