Make KedroPipelineModel compatible with a broader range of kedro version

[Galileo-Galilei]

Description

KedroPipelineModel stores several kedro objects (Datacatalog, Pipeline, Runner). Since this object is pickled, any slight change in one of the underlying kedro objects (e.g. a private attribute) prevents loading with the model if you don't have the exact kedro version used for training.

Context

This forces users to retrain model almost every time they upgrade their kedro version, which is painful when training is slow.

Possible Implementation

Store the configuration of the object (e.g. convert back DataCatalog config to a dict, and the pipeline to a json file).
