Mcquin/kitchen with travis

OH NO WHATS GOING TO HAPPEN
Rather than changing the default command to execute the tests we should have an entry in the matrix which looks something like: 
```
     - rvm: 2.1.1
        script: cd spec/e2e; bundle install; kitchen converge default-ubuntu-1204
```

This way only on one box we'll launch kitchen test. 

Also we can run `kitchen test` instead of converge which will also upload some cookbooks and run for us :smile:
