[feature] allow for dynamic model selection

[vsoch]

The model selection for deepdream can be dynamic! The container to generate the images is housed in a different repository, and this feature is documented here --> https://github.com/vsoch/deepdream-docker/issues/1

is this a generic help wanted or is it for me?

[vsoch]

Definitely not for you! It's for other developers that want to contribute down the road. It's useful to add things as you think of them so you don't forget ;)

Thanks!
