    [update] Ensure we get fresh hiera data before running update_steps.

    We need to make sure that the hiera data are fresh before the update
    step so that anyone using those data during those steps are seeing the
    latest information from heat.

    Factor out the hiera generation and include it in deployment and
    update playbooks.

    The double tasks definition in the deployment playbook seemed to be
    redundant so It has been removed.
