Ansible CloudStack external inventory script.
=============================================
Generates Ansible inventory from CloudStack. Configuration is read from
'cloudstack.ini'. If you need to pass the project, write a simple wrapper
script, e.g. project_cloudstack.sh:
#!/bin/bash
cloudstack.py --project <your_project> $@
When run against a specific host, this script returns the following attributes
based on the data obtained from CloudStack API:
"web01": {
"cpu_number": 2,
"nic": [
{
"ip": "10.102.76.98",
