* 报警规则：

`sum(rate(tikv_thread_cpu_seconds_total{name=~"raftstore_.*"}[1m])) by (instance, name) > 1.6`
`sum(rate(tikv_thread_cpu_seconds_total{name=~"raftstore_.*"}[1m])) by (instance) > 1.6`

* 规则描述：

Raftstore 线程压力太大。
代表的是 raftstore CPU 消耗, 如果高代表 Raftstore 线程压力太大。
阈值取值为 raftstore.store-pool-size 的 80%, 默认 raftstore.store-pool-size=2, 所以这里设置为 1.6。
