Dockerhub mongo image pulled by default (image with tag "latest") does not support the --smallfiles flag. This causes containers to exit after calling docker run. Specify mongo image mongo:3.4.1 to match image used in tutorial.

First, thanks for making this tutorial. I was able to complete it with some work. 👍
Problem
Unless someone manually specifies a correct old dockerhub image tag for mongo that supports the
--smallfilesflag, the replica set creation and docker machine reset scripts wont work.I think this pr is important to help people more smoothly follow the tutorial by requiring them to make less changes specific to their env.
