• issue a warning message if more then one option from attributes, remove_attributes, and update_attributes is used simultaneously for Check MK < v2.2.0p7
• fail with error message if more then one option from attributes, remove_attributes, and update_attributes is used simultaneously for Check MK >= v2.2.0p7
