Verification steps

1. Ensure you have your openshift cluster up and running
2. Delete your admin user `oc delete user admin`
3. Delete your asb namespace `oc delete project ansible-service-broker`
4. Check out this branch and run the playbook `ansible-playbook ./installer/playbook.yml -e "dockerhub_username=$DOCKERHUB_USERNAME" -e "dockerhub_password=$DOCKERHUB_PASSWORD" -e "dockerhub_org=$DOCKERHUB_ORG" --ask-become-pass`
5. There should be no errors logged in the output
6. Check that the admin user was created `oc get user admin`
7. Check that the ansible-service-broker project exists `oc get project ansible-service-broker`
8. Re-run the playbook and check that there is no errors and that the admin and asb project still exist
