Description
Create a PipelineDataFlowModel.Builder class. This will allow us to remove a constructor and have only one private constructor to be used by the builder and by Jackson for JSON deserialization.
Relatedly, the PipelineDataFlowModel should use non-empty serialization for processors. It should also return an empty List<PluginModel> instead of null to provide consistency for clients.

Research direction
Start by locating PipelineDataFlowModel and read its constructors, processors serialization, and PluginModel accessors. Add the Builder and verify that JSON deserialization still works, empty processors are omitted during serialization, and clients receive an empty List rather than null.
