Comment 1 for bug 1733869

Collecting some pointers I've recieved how to do this here:

https://docs.openstack.org/tripleo-quickstart/latest/getting-started.html#validate-the-tripleo-overcloud-is-functional

- https://github.com/openstack/tripleo-quickstart-extras/blob/master/playbooks/quickstart-extras-validate.yml
- https://github.com/openstack/tripleo-quickstart-extras/tree/master/roles/validate-tempest
- "you will see in the tq/config/general_config/featureset yaml files that different jobs install different sets of tempest plugins"
- you'll need to point tempest config at the undercloud
- Possibly can be based on scenario003
