Scenario:
1. Create cluster
2. Add 1 node with compute role
3. Add 3 nodes with controller role
4. Deploy the cluster
5. Verify network
6. Run OSTF
7. Verify configuration file on each controller
8. Apply new CPU overcommit ratio for each controller
9. Verify deployment task is finished
10. Verify nova-scheduler services uptime
11. Boot instances with flavor that occupy all CPU
12. Boot extra instance and catch the error
