| Verify the IPv6-only deployments | |
| This role needs to be invoked from a playbook that | |
| run tests. This role verifies the IPv6 setting on | |
| devstack side and devstack deploy services on IPv6. | |
| This role is invoked before tests are run so that | |
| if any missing IPv6 setting or deployments can fail | |
| the job early. | |
