Bug: kubeCmdFactory will lose WrapTransport config

[a244591052]

gitops-engine/pkg/utils/kube/resource_ops.go

Lines 150 to 160 in 95e0025

	func kubeCmdFactory(kubeconfig, ns string, config *rest.Config) cmdutil.Factory {
	kubeConfigFlags := genericclioptions.NewConfigFlags(true)
	if ns != "" {
	kubeConfigFlags.Namespace = &ns
	}
	kubeConfigFlags.KubeConfig = &kubeconfig
	kubeConfigFlags.WithDiscoveryBurst(config.Burst)
	kubeConfigFlags.WithDiscoveryQPS(config.QPS)
	matchVersionKubeConfigFlags := cmdutil.NewMatchVersionFlags(kubeConfigFlags)
	return cmdutil.NewFactory(matchVersionKubeConfigFlags)
	}

In the above code, WrapTransport is not passed, which will cause the client corresponding to the NewFactory to have no WrapTransport, which is not as expected.

In addition, RateLimiter is not passed, which will cause the NewFactory client to create a new RateLimiter using the passed in QPS. If k8s is limiting the flow for the client, then it is expected. If k8s is limiting the flow for the IP address, then RateLimiter should be passed.
