Nice to Have: Deploy script

[Bhuvan Venkatesh]

Right now you can deploy the api after knowing a good amount about the internals, setting up mongo etc.

We have codified setup in .travis.yml, but it'd be nice to refactor this to a deploy script for Ubuntu, so we can

• Use this for travis testing
• Provision machines with a one step install

I'd recommend fab, but as always there are other ways to skin a cat.
