## Feature Request

### Describe your feature request related problem

To upgrade the TiKV cluster, we will use `evict-leader-scheduler` to ensure the restart TiKV has no leader. but we encountered the problem that the `evict-leader-scheduler` was not deleted many times during the rolling upgrade process. In order to better solve the problem, we can provide a special evict leader scheduling with a timeout for the deployment tool.
