Sentinel与nacos整合推送配置后，限流数被重置

当配置限流规则为/aaa/test的qps为每分钟5次，达到次数后已被限流，这里配置qps为每分钟10次，通过nacos推送配置，调用了10次资源后才被限流，而不是在原来的基础上再调用5次后就限流，相当于只要推送的新的限流配置，之前的限流记录被重置了

Start by reproducing the Sentinel rate-limiting scenario with Nacos configuration push: consume five of five allowed requests, change the limit to ten, and observe the subsequent requests. The issue is resolved when the existing five-request count is preserved and only five additional requests are accepted after the update; no file or test entry point is named.
