Ensure `TE` headers is properly sent to gRPC upstream server in request generated from Kong. Previously, the call to `kong.service.request.set_headers` was not taking effect as the `TE` headers cannot be set through normal OpenResty APIs; this PR ensures it's set in a similar way as the `:authority` pseudo-header.

Ensure
TEheaders is properly sent to gRPC upstream server in request generated from Kong by thegrpc-webandgrpc-gatewayplugins. Previously, the call tokong.service.request.set_headerswas not taking effect as theTEheaders cannot be set through normal OpenResty APIs; this PR ensures it's set in a similar way as the:authoritypseudo-header. This fix ensures our implementation complies with the gRPC spec, which mandates aTE: trailersheader in gRPPC over http/2 requests.
