Objects created prior to enabling HDFS Sentry sync and AFTER a full snapshot don't get added to NN cache

If a full snapshot is done and the customer goes and disables HDFS Sentry sync and creates a bunch of databases (or any objects) then if they were to enable HDFS Sentry sync those objects won't be managed.

These objects are not in AUTHZ_PATHS table since they were created when HDFS sync was disabled. Also on enabling HDFS sync these objects won't get added to the AUTHZ_PATHS table since we won't do a fullsnapshot as one was already done
