Build & Release Automation

[opetch]

It would be nice to version this module, as requested in #5 a possible solution would be, to add tests using kitchen-terraform and Travis configuration that runs the tests, tags the repo and builds a release. A sufficient suite of tests would create resources and verify they're correctly created and destroyed using the AWS resources feature that InSpec has. This would be more thorough than the state verification that is used by default in kitchen-terraform due to the call out to cli in this module.
