Ansible tests with the default inventory try to connect to localhost through SSH

Summary

When you run ansible-playbook in your test and use the default inventory file, Ansible tries to connect to localhost through SSH, and fails.

Steps to reproduce

In your test, call:

ansible-playbook --inventory-file inventory my-test-playbook.yml

Expected behavior

Test tests.

Actual behavior

Test does not test (because it tries to connect to localhost through SSH).

Possible fixes

ansible_connection: "local"

Just see the service role for reference.
