    Consider hostdev devices when building metadata

    Previously, device role tagging metadata would only be built for
    LibvirtConfigGuestInterface and LibvirtConfigGuestDisk. This didn't
    account for passed through PFs, which can also be tagged and appear as
    <hostdev> in the libvirt XML. This caused device role tagging to not
    work for PFs. This patch adds support for <hostdev> devices to
    _build_device_metadata.

    NOTE(artom): Queens -> Pike backport is clean, conflicts in
    nova/tests/unit/virt/libvirt/test_driver.py in Queens due to trusted
    VFs not being present.
