Transfer orders to an updated workflow

Current Situation

• When a workflow is modified and is deployed then the workflow is assigned a new version identifier.
• If orders exist for a previous version of the workflow then both workflow versions co-exist and are visible in the Workflows view.
• Users can add orders to the latest version of the workflow. 
• Users can complete any orders being processed in the previous version of the workflow to make this version of the workflow disappear.
• Frequent reasons for new workflow versions are corrections for example applied to jobs in the workflow. In this situation users would like to transfer existing orders from the previous workflow version to the current version of the workflow.

Desired Behavior

• The feature allows to transfer all orders of an existing workflow version to the latest version of the workflow.
• The underlying implementation by Controller/Proxy is covered with JS-2028
