拼合注册IP地址问题：

//var address = dnsQuery.ResolveService("seviece.consul",serviceDiscoveryOptions.Value.UserServiceName);
            //var addressList = address.First().AddressList;

            //var host = addressList.Any() ? addressList.First().ToString() : address.First().HostName;
            //var port = address.First().Port;

            //直接读取Json配置用法
            var host = IPAddress.Parse(serviceDiscoveryOptions.Value.Consul.DnsEndpoint.Address);
            var port = serviceDiscoveryOptions.Value.Consul.DnsEndpoint.Port;

可以获取IP地址，但服务访问无法成功，留存。
