Add openfeign directly to POM

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>

Program startup report found

No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

Because the spring boot and spring cloud versions are higher, the loadbalancer dependency needs to be added

The problem is that there is no loadalanc, but note that the ribbon in Nacos will cause the loadalanc package to fail. Add it in the common POM
