`minikube kubectl --profile` does not switch context

[owenthereal]

Steps to reproduce the issue:

1. Provision multiple minikube clusters, e.g. cluster-a & cluster-b
2. Change context to cluster-a with kubectl config use-context cluster-a
3. Get namespaces in cluster-b with minikube kubectl --profile cluster-b -- get ns, context isn't switched from cluster-a to cluster-b and cluster-a namespaces are shown.

The reason is that

Lines 34 to 81 in 5ce9d99

	var kubectlCmd = &cobra.Command{
	Use: "kubectl",
	Short: "Run a kubectl binary matching the cluster version",
	Long: `Run the Kubernetes client, download it if necessary. Remember -- after kubectl!
	Examples:
	minikube kubectl -- --help
	minikube kubectl -- get pods --namespace kube-system`,

Hey @owenthereal thank you for reporting this bug. We should be taking profile into account for the kubectl command.

It should be on the easier end to fix. If you, or anyone else, would be interested in taking this issue on, please comment /assign.
