add integration tests for ansible collection

[ktdreyer]

The ./build-collection script generates our Ansible Collection tarball. It's important to test this script, because users will come to rely on the Ansible Collection over time.

We should build an integration test that tries to install this with ansible-galaxy collection install _build/ktdreyer-koji_ansible-0.0.0-git.230+9d7258a6.tar.gz and run some playbook with it.

I've added a really simple integration test in #110 . This does not run the playbooks against a live instance. It simply checks that we can build the collection and that ansible-galaxy can install the collection artifact into to the test environment.
