MINOR: Removed unnecessary Vagrantfile hack

The hack here is no longer necessary with up-to-date versions of Vagrant, vagrant-hostmanager, and vagrant-aws. What's more, the change in c8b60b63 caused a chain of infinite recursion on OSX, preventing bringup of VMs on a typical laptop.

Closes #867 from granders/remove-vagrantfile-hack and squashes the following commits:

14f4395 [Geoff Anderson] Removed uneccessary references to version 1.5.0 of vagrant-hostmanager
8799afe [Geoff Anderson] Removed Vagrantfile hack which is no longer necessary with up-to-date versions of Vagrant, vagrant-hostmanager, and vagrant-aws
