Now filters can return StopIteration from encodeHeaders, and then call addEncodedData from encodeTrailers. This allows the JsonTranscoderFilter to properly transcode gRPC status in trailer headers into a JSON reply body. Risk Level: Low Testing: unit-tests, integration tests in gRPC JSON transcoder filter.

There was a problem hiding this comment.
Can you add a similar parallel test in which the filter decode/encodeTrailers() callbacks continue to stop iteration and then do a continuation later outside of callback context?
