transformations: add support for data model destination type

[dsorenes]

Adds support for handling the data model destination. We need this in our project in order to see which type the transformation is writing to. I've tested this with both a RAW transformation and a data model transformation.

Old transformation:

I'm still not sure about the release process, but will investigate that before doing a release.
