class_docstr: Abstract base class for uploading trained model artifacts to different repositories.
  
  This class defines the interface for uploading trained model artifacts to various repositories such as Huggingface
  Hub, without specifying the concrete implementation for each repository. Subclasses of this base class must
  implement the 'login' and 'upload' methods.
docstr: Abstract method to handle authentication with the target repository.
  
  Subclasses must implement this method to provide the necessary authentication
  mechanisms required by the repository where the model artifacts will be uploaded.
  
  Raises:
      NotImplementedError: If this method is not implemented in the subclass.
