Add example of an Ansible static inventory for on-prem Geo environments

We have some examples of using an Ansible static inventory for normal environments for on-prem setups. What we don't have though is one for a Geo on-prem setup.

Task is to add in an example of an Ansible static inventory for a Geo on-prem setup. This would be best done after the Geo docs rewrite. The docs should be updated with an inline example but a full Ansible config example should be added under examples also for reference.
