    Implement minor update workflow with config download

    This change aim to refactor the way of doing the minor upgrade
    via ansible playbook download by the config download
    It will depend on a mistral change which will get the
    ansible update_task and run it via mistral
    The user will have two ways for performing the minor update:
      - the stack update command which will make an automatic minor
        upgrade (or just upgrade a given set of nodes)
      - running it manually via ansible on the undercloud
