Should we optimize the code to avoid using magic number .Or Are there other considerations.

[Zhenbing Feng]

 When I configure `shenyu.httpclient.strategy=netty ` to use
 NettyClientResponsePlugin.


I have found some magic number here in NettyClientResponsePlugin

@Override
public int getOrder() {
    return 100;
}

@Override
public String named() {
    return "NettyClientResponse";
}


 Should we optimize the code to avoid using magic number like this

@Override
public int getOrder() {
    return PluginEnum.RESPONSE.getCode();
}

@Override
public String named() {
    return PluginEnum.RESPONSE.getName();
}
