感觉像上面那样用个常量，用 nicType = util.VethType 会更好些

"not enough arguments in call to csh.deleteNic", 前面的函数调用需要，这里得去掉最后一个参数了

Describe
当删除pod时，若pod被直接删除cni来不及处理时，通过
pod, err := csh.Controller.podsLister.Pods(podRequest.PodNamespace).Get(podRequest.PodName)获取pod进行后续的处理条件，会导致此时无法处理，直接在k8serrors.IsNotFound中返回。复现
例如 在pod的部署yaml中设置了terminationGracePeriodSeconds: 0，导致 Pod 在删除 Deployment 后被立即终止，而 CNI 插件的 handleDel 函数还没来得及处理删除网卡的操作。
使用 podRequest.ContainerID 来识别 Pod，而不是使用 podRequest.PodName。这样即使 Pod 已经被删除，CNI 插件仍然可以通过容器 ID 来删除网卡。
