Default grafana dashboard doesn't work if applications deployed in other namespace

[psibi]

Summary

When you use the default grafana dashboard provided by Argo rollouts, it's not giving any options to select other namespace apart from the one where the controller is deployed.

Diagnostics

What version of Argo Rollouts are you running?

❯ kubectl argo rollouts version
kubectl-argo-rollouts: v1.1.1+0716c5d

  Compiler: gc
  Platform: linux/amd64

This is the image I'm using:

containers:
- image: "quay.io/argoproj/argo-rollouts:v1.1.1"

I'm not pasting any logs from the pods as I think they are irrelevant for this issue. But let me know if that's required.

Debugging this issue further, it seems the issue is because there are two labels being exported by prometheus:

• namespace: the namespace where controller is
• exported_namespace: the namespace where the application is present.

I believe the best way to fix is this is create a another set of dashboard for this use case.
