calico性能测试
硬件环境：
三台虚拟机：
192.168.99.129 master（kube-apiserver、kube-controller-manager、kube-proxy、kube-scheduler、kubelet、etcd、calico、docker）
192.168.99.130 slave1（kube-proxy、kubelet、etcd proxy、calico、docker、dns）
192.168.99.131 slave2（kube-proxy、kubelet、etcd proxy、calico、docker）
软件环境：
kubernetes 1.5.2
etcd 3.1.0
calico 0.23.1
qperf （网络性能测试工具，安装方法：yum install -y qperf）
测试结果：
