Description

## Feature Request

### Describe your feature request related problem

During fast DDL, many empty regions will be split and then scattered to different tikvs.

However, it will slow down the tikv raftstore, leading to a duration spike as follows.

It would make the cluster more stable if we could limit the scatter speed.
