多实例（主要是v2ray多实例）需求，主要是两个场景，且难以用其它方式替代。请拨冗考虑，未来是否可以增加此特性。

场景1、代理链式转发

在 #742 中关于代理链式转发的讨论，使用proxySettings代理出站流量的方向是对的，但在实操中，结合机场的订阅，需要将机场的信息编辑到复杂路由的json配置中，当切换线路时非常的麻烦。

我现在的做法，是机场的代理提供一个本地socks5服务，比如端口为10801，v2ray中配置一个socks协议的outbound，作为vmess的proxySetting。整个链路大致是这样的:

  浏览器  -> 
  # 代理
  socks://127.0.0.1:1080 -> vmess outbound (proxySetting on socks)-> socks outbound -> 
  #
