How to: Structure idea
The basic idea to define 3 levels of application kustomization:
* base level inside apps/base defines a common definition of application and values for everything
* bundles level inside apps/bundles defines aggregation of the base application and kustomization for the specified bundle
* cluster level inside clusters/[cluster_name] defines entry point where we can include some bundle and override cluster-specific values or add something more
