This fixes the remaining Python 3 syntax errors, so re-enable compileall for contrib/ again.
Paramiko module is used to parse ssh_config. Added multi-vm support Added "_meta" element https://docs.ansible.com/ansible/developing_inventory.html#tuning-the-external-inventory-script
renamed plugins to contrib (they are not really plugins) rewrote README.md to reflect new usage added new dir to setup.py so it gets copied with installation, in views of making using inventory scripts easier in teh future
