[OSTF] Test network connectivity to instance which is running on node with enabled DPDK

[Artem Panchenko]

We need to create new OSTF tests which spawns new instance on compute with DPD and checks connectivity to it via floating IP:

Check network connectivity from instance with DPDK via floating IP
        Target component: Neutron
        Scenario:
            1. Create a new security group (if it doesn`t exist yet).
            2. Create router
            3. Create network
            4. Create subnet
            5. Uplink subnet to router.
            6. Create new flavor with huge pages
            7. Create an instance using the new flavor, security group
               in created subnet. Boot it on compute with enabled DPDK.
            8. Create a new floating IP
            9. Assign the new floating IP to the instance.
            10. Check connectivity to the floating IP using ping command.
            11. Check that public IP 8.8.8.8 can be pinged from instance.
            12. Disassociate server floating ip.
            13. Delete floating ip
            14. Delete server.
            15. Delete flavor
            16. Remove router.
            17. Remove subnet
            18. Remove network
        Duration: 300 s.
