Implement business rules for measure handling per function

[ravimeijerrig]

Description

We will use a ‘Flexible function allocation’ on measure-level. In this ticket we implement the business rules per function.
For all measures:

• All team members can see all measures and function allocations.

Permissions of the functions per measure:

• Verantwoordelijke/Accountable can move tasks from any state to any state
• Uitvoerende/Responsible can move tasks to 'te doen' 'uitvoerend' en 'review'
• Controlerend/Reviewer can move task from 'review' to 'done'
• Other non-assigned team members cannot move a task.

	Verantwoordelijke/Accountable	Uitvoerende/Responsible	Controlerend/Reviewer
Move task to ‘To do’ ‘Doing’ ‘Review'	X	X	X
Move task to ‘Overslaan’	X
Move task to ‘Done’	X		X
Assign Verantwoordelijke/Accountable	X	X	X
Assign Uitvoerende/Responsible	X	X	X
Assign Adviserend/Consulted	X	X	X
