UI: provide cluster namespace when fetching kbueconfig

When a cluster is created in a namespace that's different from the
default one ("default") then downloading the kubeconfig failed because
the UI didn't provide the cluster's namespace to the server.

With this change, the namespace is provided as a query parameter.
