QUIC: reject streams which we could not create. The reasons why a stream may not be created by server currently include hitting worker_connections limit and memory allocation error. Previously in these cases the entire QUIC connection was closed and all its streams were shut down. Now the new stream is rejected and existing streams continue working. To reject an HTTP/3 request stream, RESET_STREAM and STOP_SENDING with H3_REQUEST_REJECTED error code are sent to client. HTTP/3 uni streams and Stream streams are not rejected.
