Update vagrant

Closes #199 

This adds a couple scripts to launch a rails console and run the spec suite. They can serve as guides for how to run other rails services from inside docker. 
This rake schema load task will destroy all data in the db. If we want to persist data between provision attempts then this should be run manually via the rails console or we create a script that the user runs manually. 

If you can think of a way to run this once only on the first provision this would be fine as well.
