Need a script to automate the Ec2/Backend setup and configuration.

Steps might include but aren't limited to:

• Install required packages & sw (like python, gunicorn, nginx, etc)
• sw configuration (set nginx proxy for port, etc.)
• clone and setup GitHub repo
• install python dependencies via requirements.txt
• run unit tests and verify
• Automate django configuration settings #23
• run python web-server (with port ex. 8000), nginx proxy server, gunicorn, etc.
