feature request 请问是还没有通过dashboard推送熔断规则到dataSource得功能吗?

## Issue Description

Type: *bug report* or *feature request*

### Describe what happened (or what feature you want)
看代码是由flowV2但是缺少degradeV2得代码

### Describe what you expected to happen
是不是应该有对应的熔断得持久化?

The issue mentions flowV2, degradeV2, dashboard, and dataSource; start by tracing those components and how circuit-breaker rules are persisted. Confirm the expected dashboard-to-dataSource behavior and define completion around consistent persistence and propagation of those rules.
