When importing legacy Data Query Templates, the Template can become unusable #5426
Description
Describe the bug
In Cacti 1.2.23, we changed the index_type, index_value, and output_type to be always checked. Unfortunately, some older Cacti Data Templates did not have this enabled upon export. This causes those Data Query Data Templates to break post Cacti 1.2.23.
Expected behavior
Account for these Damaged Data Templates on import.
