[Permissions] Create new permission for adding of Assignment and Quiz etc to Assignment Groups and for Adding/Editing Assignment Groups

[StephanieNg]

Problem statement:

As administrators, we build up the course for the lecturers in the course blueprints which are then sync out to the associated courses when term starts. In the blueprints, we have created the assignments and quizzes and assign them to the correct assignment groups with the correct weightage and rules set Unfortunately, our lecturers causes downstream issues by accidentally 1. shifting the assignment/quiz within an assignment group (eg A) to another assignment group (eg B) 2. editing the rules set on an assignment group

Proposed solution:

If the permission to manage assignment groups are separated from the permissions to manage assignments and quizzes, this would minimize downstream impact

User role(s):

admin

Would be ideal to separate the assignment and quiz permissions from each other too
