Function blackout_target::set_up_partition

pub async fn set_up_partition(
    partition_label: &str,
    device_dir: Option<&DirectoryProxy>,
    skip_ramdisk: bool
) -> Result<ControllerProxy>

During the setup step, formats a device with fvm, creating a single partition named [partition_label]. If [device_path] is None, finds a device which already had fvm, erase it, and then set it up in this way. Returns the path to the device with the created partition, only once the device is enumerated, so it can be used immediately.
