Build new docker images in build_model with in-memory Dockerfile

[dcrankshaw]

Removes the need to write a Dockerfile to disk in the user's file system by creating an in-memory Dockefile with StringIO then adding it directly to a temporary tar file to be used as the Docker build context.

The end result is that we don't write (and potentially overwrite) Dockerfile's in the user's system.

Looks good! Part two of the tutorial needs to be updated to remove the force argument from build_and_deploy_model. Once that's done, I'll merge.

Good catch. Fixed.
