Add Vagrantfile

Prior to this commit we did have a vagrant workflow for testing
the virtual machines. This commit adds a Vagrantfile with
4 boxes that will use the box file created when you `rake
everything['Centos']`. This allows you to rebuild the vm and `vagrant up
master` and the related student system i.e. `vagrant up fundamentals`
Add ssl_listen_address console rake task

Prior to this commit the testing for advanced on vagrant did not work
because vagrant has multiple interfaces and puppetdb is only listening
on one. This commit adds a console param, that probobly might eventually
be baked into the advanced module when rake tasks are not so horribly
slow.
