Application framework only supports one type of models
Description
Currently, it is only possible to use one type of models with the application framework, see application-framework/models/model-handling.go
. It uses arista models, but when trying to build an app with other models than the arista ones, an error gets thrown during the unmarshall process. Something with not being able to mix different kind of models during this process.
Some way of supporting different kind of models would be really helpful herer, as the framework is supposed to be used to build applications fast without any further hassle.
