Add app info sub-command

Add app info sub-command to show post install instructions for an app and the app homepage link, so that users don't have to unnecessarily install again to see them, which was the only way till now to see post install instructions.

This commit adds info for nginx-ingress, cert-manager, metrics-server, tiller, linkerd, cron-connector, kafka-connector, minio, postgresql, kubernetes-dashboard, istio, abd crossplane

Fixes: #133
