service startup failed when Servicecomb engine one node down, because necessary configs for service startup cannot be obtained

[chengyouling]

sdk版本：
servicecomb-java-chassis 2.6.0

现象：
测试模拟Servicecomb引擎单节点故障情况下，启动服务发现连接配置中心失败，导致服务启动必要配置无法获取，服务启动失败。

客户考虑有问题的场景：
容器根据请求流量对服务pod动态扩容的过程是不确定的，无法确定引擎节点在这期间是都可用的，可能会有注册失败问题。
