This a placeholder for the ability to add a subworkflow to an existing workflow as a service.
Configuration parameters include:
Category: used for the display of the drop-down list of workflows in the Workflow Builder.
Each workflow is displayed under its own category. The list of categories can be configured
properties.json under the key
"property_list" / "workflow" / "category".
Close Connection: Once the subworkflow is done running, the current
connection will be closed.
Superworkflow: Select from a workflow from the list that will act as a
superworkflow. The superworkflow must have added the
service to indicate when this workflow will execute.
