Refactor transformObject to implement Encoder interface

[wojtek-t]

Long-term, transformObject:

kubernetes/staging/src/k8s.io/apiserver/pkg/endpoints/handlers/response.go

Line 40 in 5219ad7

func transformObject(ctx context.Context, obj runtime.Object, opts interface{}, mediaType negotiation.MediaTypeOptions, scope *RequestScope, req *http.Request) (runtime.Object, error) {

should be refactored so that it implements Encoder interface (and it has nested encoder inside):

This would allow us to cache the results for difference media.Convert options, which currently is not supported:

kubernetes/staging/src/k8s.io/apiserver/pkg/endpoints/handlers/response.go

Line 50 in 5219ad7

// TODO: Long-term, transformObject should be changed so that it

To implement Encoder interface, the negotiation.MediaTypeOptions would be passed to the class where transformation code (Encode()) resides, right ?
