react/connector 组件支持单个View 组件链接多个Service

[wewoor]

目前 connect 函数只能链接单个 service/view/controller, 如下：

const PanelView = connect(panelService, Panel, panelController);

考虑支持如下场景：
单个组件链接多个Service state, 用法例如：

const PanelView = connect({
  A: serviceA, 
  B: serviceB
}
, Panel, {controllerA: controllerA, controllerB: controllerB}
);
