func WalkTemplates

WalkTemplates walks through all templates of a GeneratePatchesRequest and calls the mutateFunc. By using walk templates it is possible to implement patches using typed API objects, which makes code easier to read and less error prone than using unstructured or working with raw json/yaml. Also, by using this func it is possible to ignore most of the details of the GeneratePatchesRequest and GeneratePatchesResponse messages format and focus on writing patches/modifying the templates.
