ASO v2 already has support for AppConfiguration - we should add support for the child resource [KeyValues ](https://learn.microsoft.com/en-us/azure/templates/microsoft.appconfiguration/configurationstores/keyvalues?pivots=deployment-language-arm-template)as [requested via Slack](https://kubernetes.slack.com/archives/C046DEVLAQM/p1695419290155819). We should also investigate support for _Replicas_ and _Private EndpointConnections_.
