Add test for Ansible Tower Inventory syncing

Report template named 'Ansible Inventory' (default name is specified in settings) must be present in Satellite 6.7 and later in order to provide enhanced functionality for Ansible Tower inventory synchronization with Satellite.
This test checks that the proper template is present on the Satellite side and that it is renderable by a user with minimal required permissions.
