business rules : add criterion "redactor", "redactor in group", "technician in group"

Hello,

Currently in GLPI 9.1.5, you can't do actions based on criterion like "redactor" (creator), "redactor in group" or "technician in group"

It would be realy useful in order to make a business rules like that :  

• if redactor in IT Group, assign IT group to ticket (if tickets aren't auto assign to redactor)
• if technician in IT Group, assign IT group to ticket

Currently you can't do that simply.
