Fix Ansible manage inventories role (redhat-cop#651)

* Split create vs update inventories

* Use original register name

* Add Debug message

- Add a debug message to try and catch if some people are receiving an empty JSON result from the Tower API.

* Ensure register var is reset each loop execution

* inventory_output to inventory_output_update

Renaming inventory_output to inventory_output_update for consistency

* Update process-inventory.yml
