bug: apisix 3.9.1 does not support apisix-seed for service discovery

[bwangll]

Current Behavior

error日志中直接报错服务发现 nacos未init

Expected Behavior

apisix服务发现不应该受限于自身配置

Error Logs

[error] 4141#4141: *1791018 [lua] init.lua:548: handle_upstream(): failed to set upstream: discovery nacos is uninitialized

Steps to Reproduce

1.使用apisix配置服务发现为nacos 2.使用apisix-seed做服务发现控制平面 3.上游信息同步后。进行路由访问，被apisix拒绝。因为没有在apisix中配置nacos
