I could not find any trouble in all of npm commands, but few problems in UI.

When I logged in with token for kubernetes-dashboard namespace made by aio/deploy/recommended.yaml and selected namespace as kubernetes-dashboard:

• Replicaset made by recommended.yaml could not get its YAML in Edit view. Browser console shows error 404.
• In secret list view, Opaque type secrets made by recommended.yaml could not get its YAML in Edit view. Browser console shows error 404.
• In secret list view, kubernetes-dashboard-certs and kubernetes-dashboard-key-holder made by recommended.yaml has Edit menu, but it could not get its YAML and got 401 error. If user does not have permission, it's better to hide Edit menu, I think.

However, we could describe these problems as known issues and merge this PR, I think.

Edit for resources that the user has access to has to work, as it works with v1.15 now. Last issue exists on the current master I think, so we can create an issue for that and fix later.
