As a user, I should be able to introspect 2 flatpak remotes : Redhat registry and Fedora
The introspection will reach out to the index, identify the repositories and create remote repositories from the index. 

The remote flatpak repositories will be a new model in katello and will contain information we recieve from the index json. 

Reruns of the introspection task should update the remote repositories if any changes have occurred.
