It would be great to include a sample that demonstrates how to use ArgoCD applicationset to deploy an application to multiple clusters. I took the existing book import application that uses channel/subscription and made it work with Argo ApplicationSet. Can submit a PR

I am trying to use a subscription to place the htpasswd secret on a managed cluster into the openshift-config namespace and the source namespace should not be openshift-config for the secret,application,subscription,channel as this would mess with the hub cluster configuration and there should be isolation. How do I configure the namespace to source from namespace A (workshop) and place into namespace B (openshift-config).
