wanghancai opened a new issue #512: 服务重新注册成功后更新属性失败
URL: https://github.com/apache/servicecomb-service-center/issues/512
 
 
   服务重新注册时，只要查到实例就不会再更新ttl导致，长时间出现实例实例下线；需要SC收到注册并返回成功前重置ttl
   func (s *InstanceService) Register(ctx context.Context, in *pb.RegisterInstanceRequest) (*pb.RegisterInstanceResponse, error) {
   	remoteIP := util.GetIPFromContext(ctx)
           ........
   	instance := in.GetInstance()
   
   	//允许自定义id
   	//如果没填写 并且endpoints沒重復，則产生新的全局instance id
   	oldInstanceId, checkErr := serviceUtil.InstanceExist(ctx, in.Instance)
   	if checkErr != nil {
                   .......
   		return &pb.RegisterInstanceResponse{Response: resp}, nil
   	}
   	if len(oldInstanceId) > 0 {
   		log.Infof("register instance successful, reuse service %s instance %s, operator %s",
   			instance.ServiceId, oldInstanceId, remoteIP)
   		return &pb.RegisterInstanceResponse{
   			Response:   pb.CreateResponse(pb.Response_SUCCESS, "instance more exist"),
   			InstanceId: oldInstanceId,
   		}, nil
   	}
