How to get current namespace when creating a custom list view?

[fengye87]

What steps did you take and what happened:
I was trying to write a plugin that supports a custom resource list view. When listing objects, how can I get current user selected namespace?

router.HandleFunc("*", func(request service.Request) (component.ContentResponse, error) {
	podList, err := request.DashboardClient().List(request.Context(), store.Key{
		Namespace:  "default", // TODO: how to get current namespace?
		APIVersion: "v1",
		Kind:       "Pod",
	})
	if err != nil {
		return *contentResponse, err
	}
	...
})

Environment:

• Octant version (use octant version): 0.25.1
• Kubernetes version (use kubectl version): 1.23.5
• OS (macOS 10.15, Windows 10, Ubuntu 19.10 etc): Fedora 35
