htable: control load/save of expires value from db via parameter

- db_expires - a new paramter to control if the expires of the items in the hash table should be loaded/saved to database - default is 0 - do not load/save expires value - backward compatibility, since there might be hash tables loaded form database but without expires - if the hash table definition does not have an auto-expires, even if db_expires=1, the expires column is not selected since it is not needed
