      Recursively convert Hydra 0.x configs to Hydra 1.x configs.
  
      Changes include:
      -   `cls` -> `_target_`.
      -   `params` -> drop params and shift all arguments to parent.
      -   `target` -> `_target_` cannot be performed due to ModelPT injecting `target` inside class.

          cfg: Any Hydra compatible DictConfig

          An updated DictConfig that conforms to Hydra 1.x format.
