调用k8s的api进行修改主机操作报这个错误：

Operation cannot be fulfilled on nodes "node--mjsbyov0-15": the object has been modified; please apply your changes to the latest version and try again

经过一番折腾，终于发现是传入的值有问题，metadata中应该去掉"resourceVersion": "17087854",这个字段

正确的request body如下：

{
    "metadata": {
        "name": "node--mjsbyov0-15",
        "selfLink": "/api/v1/nodes/node--mjsbyov0-15",

        },
