Update model version upload flow

Depends https://gitlab.com/teklia/arkindex/backend/-/issues/1404

A small update is required to support the new flow:

• update parameters of base methods to create and update model versions
• update TrainingMixin.publish_model_version flow

As the publication is pretty high level, it does not need directly impact workers.

You'll need to patch the workers themselves to support the metrics though... (other issues)
