    Ironic: Lightweight fetching of nodes

    The Ironic API version >= 1.8 supports fetching only a small number of
    a resource instead of it's full representation. This patch is pinning
    the API version for Ironic at 1.8 so the nova driver can benefit from
    this feature by fetching only the required fields for the deployment,
    making it more lightweight and improving the readability of the logs.

    The configuration option "api_version" was marked as deprecated and
    should be removed in the future. The only possible value for that
    configuration was "1" (because Ironic only have 1 API version) and the
    ironic team came to an agreement that setting the API version via
    configuration option should not be supported anymore.
