Issue description
目的：想要根据分流规则，比如-H "user-name:test"，改变Host让流量跑到k8s集群中不同的ingress。
实现方法：使用nginx做为ingress controller，流量根据规则转向同一个k8s里的不同ingress。apisix的route中，nodes里面填的是同一个k8s集群ingress controller的地址，根据规则把upstream_host改为ingress服务的host。详细配置见下面
遇到问题：traffic-split里面的upstream通过upstream_host字段不能正确改变Host值，访问时报错404，不把upstream配在traffic-split里时没问题

traffic-split插件中upstream_host改变没生效，流量到不了相应host的ingress，报错404
