Sample History Workflow

We would like to have a sample history workflow that allows us to track in chronological order (when possible), the activities in which a Sample (Entity) has been referenced. After playing around with it in this branch and the HZB ELN from @g-michaelgoette, we could reach some automated workflow graphs (after reprocessing the uploads).

• Create a normalizer from a class inheriting from Entity or Entity itself for the workflow.
• Investigate if Making Activities also a Task is the only way for this.
  • If Task needs to stay, hide properties in Activities coming from this class
• Make sure that the entry_type does not become Workflow and that it keeps its original name.
