| ScaleInInstancesResponse | AsClient. ScaleInInstances(ScaleInInstancesRequest req)为伸缩组指定数量缩容实例,返回缩容活动的 ActivityId。
 伸缩组需要未处于活动中
 伸缩组处于停用状态时,该接口也会生效,可参考[停用伸缩组](https://cloud.tencent.com/document/api/377/20435)文档查看伸缩组停用状态的影响范围
 根据伸缩组的`TerminationPolicies`策略,选择被缩容的实例,可参考[缩容处理](https://cloud.tencent.com/document/product/377/8563)
 接口只会选择`IN_SERVICE`实例缩容,如果需要缩容其他状态实例,可以使用 [DetachInstances](https://cloud.tencent.com/document/api/377/20436) 或 [RemoveInstances](https://cloud.tencent.com/document/api/377/20431) 接口
 接口会减少期望实例数,新的期望实例数需要大于等于最小实例数
 缩容如果失败或者部分成功,最后期望实例数只会扣减实际缩容成功的实例数量 |

       and any explicit key, i.e Foo, set via .setFoo("value") will be a deep copy. |
