    Ensure nova-api is running before starting nova-compute containers

    If nova-api is delayed starting then the nova_wait_for_compute_service
    can timeout. A deployment using a slow/busy remote container repository is
    particularly susceptible to this issue. To resolve this nova_compute and
    nova_wait_for_compute_service have been postponed to step_5 and a task
    has been added to step_4 to ensure nova_api is active before proceeding.
