- Special handling for identity compressor to ensure compress flag is not turned on. Identity compression is a special case, and for compatibility it should not be treated as a normal compressor. - If a gRPC service is not found, include ":status" header in response to comply with gRPC spec - A few null checks were missing in GrpcRouteHandler - New tests for all the changes above
