Capability ApplicationSet

Introduction

Cluster administrators can configure the ApplicationSet to be used for this specific capability. Imagine a cluster-wide ArgoCD to manage capabilities for Paas'es. It is deployed in the namespace paas-capabilities-argocd. To enable any capability, spec.clusterwide_argocd_namespace needs to be set to paas-capabilities-argocd, so that the Paas operator will locate ApplicationSets for capabilities in this namespace. And for a new capability (e.a. new-capability), there should be an ApplicationSet to manage resources for this new capability. This ApplicationSet should be created in paas-capabilities-argocd, and it's name (e.a. new-capability) should be configured in PaasConfig (spec.capabilities["new-capability"].ApplicationSet). After setting this configuration, for every Paas with the capability new-capability defined, the Paas operator will GET the ApplicationSet paas-capabilities-argocd.new-capability, add the Paas to the list generator and update the ApplicationSet definition. This in turn will create a new Application for the capability for this Paas, and ArgoCD will create and manage the resources.
