Data Protection Request from any document (Global Action). 
These requests are managed by data protection manager who can delete
compromised data on any document (Script proxyfied by role Manager).
Once the data protection manager reviewed the Data Protection Request, he can delete
some properties on related document or delete all comments in workflow history.
Each clean up operation is stored on document as comment in edit_workflow,
in order to track data regression.
