Bug Report
当只有一个tikv一个TiFlash节点时，缩容TiFlash组件报错，提示信息如下：
- What did you do?
当只有一个TiFlash节点时，缩容TiFlash组件报错，提示信息如下：
[PD:core:ErrStoresNotEnough]can not remove store 68 since the number of up stores would be 1 while need 3
使用tiup cluster scale-in也报相同的错误。这个控制不是TiKV的么？
- What did you expect to see?
tiup cluster scale-in '1.1.1.1:9000';
移除tiflash
- What did you see instead?
tikv的配置不应该影响tiflash
- What version of TiUP are you using (
tiup --version)?

Research direction
Start with the tiup cluster scale-in entry point and reproduce the failure using one TiKV and one TiFlash node. Trace why the TiKV store-count requirement blocks TiFlash removal; done means the TiFlash node can be removed without applying the unrelated TiKV constraint.
