Resolves: #462922

Summary: Import of data does not record timestamps
Description: Added a static function import_add_created_attrs to add
ModifiersName, CreateTimestamp, ModifyTimestamp to each imported entry.  I
also added a check if nsslapd-lastmod is on or off.  It adds the created info
only if the lastmod is on.
