The evict leader has waited too long during the upgrade. How to skip this step for a quick upgrade?

You can specify `--force`. Then the processes of transferring `PD` leader and evicting `TiKV` leader are skipped during the upgrade. The cluster is directly restarted to update the version, which has a great impact on the cluster that runs online. Here is the command:

```
tiup cluster upgrade {cluster_name} {version} --force
```
