Feature Request: Scenario Template & Contribution Guide

[TeneBrae93]

I recently created a CloudGoat scenario and spent much of my time understanding how it should be set-up/formatted in Terraform so that it uses the correct profile, applies the whitelist to any public resources, etc.

To help others, it would be great to have the following:

• Contribution Guide: A guide that provides a high-level overview of how to contribute scenarios to CloudGoat

• Scenario Template: A basic scenario template that implements IP Whitelisting and the Cloudgoat profile as a starter scenario
