SSH to multiple servers over bastion

• Install dependencies

  pip3 install -r ./requirements.txt

• Given a configuration in config.yaml with structure

  server1:
      ip: 192.168.0.1
      bastion: 212.186.105.45
  serverN:
      ip: 192.168.0.2
      bastion: 212.186.105.45

• We can use a simple python helper like this

  bastion-ssh.py -i ./path/to/private/certificate -c ./path/to/config/file name-of-server
