What would you like to be added?

Propose a design doc about how to configure different attributes of a resource existing across multiple clouds.

Why is this needed?

Differences in configurations are inevitable for a resource that exists across multiple clouds. We have abstracted common parts of the same kind of resource that exist across multiple clouds, but the different parts are not included in our AppConfig model. They are also necessary because App dev or Platform dev needs to configure them in some scenarios.
