- When merging (3way) resources use the patch strategy from the openAPI if the definition exists for the field - Allow disabling of guessing patch strategy merge keys when no definition exists - Support defining strategy and key directly on configuration fields through line and header coments - Support attaching schema to parent fields of lists, and propagating -- e.g. that a field is a PodTemplate
