Automated tests for selectable Offloading types

Automate Scenarios will be:
Ubuntu

Case 1:
Deploy cluster with new offload modes and Nova flat
    Scenario:
    1. Create cluster
    2. Add 1 node with controller role
    3. Add 1 node with compute role and 1 node with cinder role
    4. Setup offloading types for the interfaces
    5. Run network verification
    6. Deploy the cluster
    7. Run network verification
    8. Run OSTF
    9. Verify offloading modes on nodes

Case 2:
Deploy cluster with new offload modes and Neutron GRE
    Scenario:
    1. Create cluster
    2. Add 1 node with controller role
    3. Add 1 node with compute role and 1 node with cinder role
    4. Setup offloading types for the interfaces
    5. Run network verification
    6. Deploy the cluster
    7. Run network verification
    8. Run OSTF
    9. Verify offloading modes on nodes

Case 3:
Deploy cluster with new offload modes and Neutron VLAN
    Scenario:
    1. Create cluster
    2. Add 1 node with controller role
    3. Add 1 node with compute role and 1 node with cinder role
    4. Setup offloading types for the interfaces
    5. Run network verification
    6. Deploy the cluster
    7. Run network verification
    8. Run OSTF
    9. Verify offloading modes on nodes

Case 4:
Deploy cluster with new offload modes, bonding and Neutron VLAN
    Scenario:
    1. Create cluster
    2. Add 1 node with controller role
    3. Add 1 node with compute role and 1 node with cinder role
    4. Setup offloading types for the bonds
    5. Run network verification
    6. Deploy the cluster
    7. Run network verification
    8. Run OSTF
    9. Verify offloading modes on nodes
