    Updates: run host_prep_tasks between update tasks and deployment tasks

    We should re-run host_prep_tasks as part of the minor update, to make
    sure the host is ready for starting the updated containers. The right
    place for them is between update tasks and deployment tasks.

    This is important in case we deliver changes to host_prep_tasks during
    minor update, or if update_tasks do something that would partially
    undo the host preparation, e.g. clear/delete some directories on the
    host to get rid of previous state.
