Describe the feature request
In a multi-cluster scenario, we execute istioctl ps, output the following content:
$istioctl ps

However, sometimes we expect to see the cluster name of a pod in multi-cluster mesh
Describe alternatives you've considered
We can add the CLUSTER column in the output of istioctl ps command , like:
$ istioctl ps
