• Refactor the Kubeflow Pipelines processor to generate Python DSL as intermediary output format
• Expose the generated DSL in the export wizard in addition to the already support static configuration file (YAML)

Additional context

• The changes have no impact on regular users because the changes are completely transparent.
• Advanced users will be able to customize the generated Python DSL, if desired.
• With these changes in place, support for pipeline parameters can be added.
