An easier way to setup ODK Aggregate for testing

Hi all,

For those who need to spin up a quick ODK Aggregate server for
testing, I've just put out a Vagrant/Ansible config at

I'm hoping to eventually add support for deploying to an arbitrary
cloud server (e.g., Digital Ocean, Linode, Google Cloud). If you are
familiar with Vagrant/Ansible, I'd love pull requests to make that
