IMPALA-8338 : Check CREATION_TIME while processing DROP_DATABASE events.

Process the drop database event only if the CREATION_TIME of the
catalog's database object is lesser than or equal to that of the
database object present in the notification event. If the
CREATION_TIME in the notification event object is lesser than
the catalog's DB object, it means that the Database object
present in the catalog is the latest and we can skip the event
instead.

Testing :
 - Added unit tests in MetastoreEventsProcessorTest.
 - Enabled testCreateDropCreateDatabaseFromImpala as
   we now have CREATION_TIME in the notification events.
