Adjust `ConfiguConfigStore` for the `Approval Queue` feature

[Richard Akman]

Suggestion

The ConfiguConfigStore class set method currently doesn't acknowledge that configs might not have been mutated but instead inserted into an approval queue for admin review. To indicate to users of the store, the method should throw an exception in this scenario.

Motivation

Improved UX and clarity to users of ConfiguConfigStore
