feat(proxy): Forward Trailers in responses (#4215)

What does this change do?

This pull request allows Trailers to be properly forwarded in chunked
transfer encoding in HTTP/1.1 and for HTTP/2 in HEADERS frames after
DATA frames.

Why is it needed?

To enable gRPC traffic to be proxied via skipper, the Trailers need to
be properly forwarded for HTTP/2 traffic.
