Description

In https://github.com/lyft/envoy/pull/1079 @lizan has implemented transcoding that requires the proto definitions to be available to envoy and up to date. This is a great start, but as discussed, the real killer feature here IMO is to do it transparently using reflection. Theoretically this should be possible.
