A general comment about the naming of package and object:
e.g. The interface RepositoryProvider defined in pkg/repository/repoprovider/repo_provider.go
Usually, we define it as an interface called Provider in pkg/repository/provider/provider.go

And similar for the package:
pkg/repository/repoconfig/aws.go -> pkg/repository/config/aws.go
