Support AWS Instance Profiles

[Ardiea]

As a DevOps person, I would like this app to support using instance profiles for determining IAM permissions, rather than explicit IAM Role and dynamic and/or static credentials.

I think maybe the app should support both methods, so developers can continue to use Access Keys. But the deployed env should use the instance profile.

Right now the App will not start without the two access key vars populated.
