Refactor chart to allow namespace replication
Currently, we are only allowing cluster replication for resources, however this is not enough as some conflicts might arise if we have namespaced resources being replicated as cluster resources. For instance, if we have two resources with the same name in different namespaces then OPA will only import the latest resources.
