Kapp-controller value schema for packages should show required configuration

As part of kctrl (kapp-controller CLI) command - kctrl package available list", there is requirement to show whether there is a required configuration that should be provided (e.g. external-dns does not work without providing the required data-values).

1. Can we derive this information from value schema in kapp-controller package?
2. Will adding certain meta-data help derive this information?

Start with the kctrl package available list command and the kapp-controller package value schema; determine what schema information is available and whether metadata is needed. Done means the command can clearly indicate when required configuration exists, with behavior agreed for the schema and metadata cases.
