Generate /etc/hosts for AWS hosts

AWS hosts get unpredictable names, and Valentino Volonghi's script got old, so I updated it to generate local /etc/hosts only.

Install

pip install -r requirements.txt
sudo cp /etc/hosts /etc/hosts.default

And configure your aws CLI with aws configure.

Running

./gen_hosts.py
sudo cp etc_hosts /etc/hosts
