    Run nova-cell_v2-discover_hosts at step 5

    We need to run nova-cell_v2-discover_hosts at the very end of the
    deployment because nova database needs to be aware of all registred
    compute hosts.

    1. Move keystone resources management at step 3.
    2. Move nova-compute service at step 4.
    3. Move nova-placement-api at step 3.
    5. Run nova-cell_v2-discover_hosts at step 5 on one nova-api node.
    6. Run neutron-ovs-agent at step 5 to avoid racy deployments where
       it starts before neutron-server when doing HA deployments.

    With that change, we expect Nova aware of all compute services deployed
    in TripleO during an initial deployment.
