This naive (and untested) implementation of a hiera 5 backend makes it possible to look up environment variables in puppet.
This backed is a data_hash type of backend and it is configured without "path" or "uri" in hiera.yaml. This means that function will be called once during the life of one hiera instance (one compilation). This means we do not have to worry about performance.

The function is now updated to not accept any options. Earlier it required a "path".
