[Assignments] Allow limiting teachers to individual assessments within a course

[Andrew42]

Problem statement:

We offer some units of study where guest lecturers/tutors teach only one topic within a course. These tutors may then be required to grade a related assessment and do not need to see any other assessments within the course. However all assessments for a course are shown to teachers within the course and in the To Do lists/calendar. Because users with teacher-type roles within a course see all assessments, we have had instances where these tutors have thus marked the wrong assessment. While these tutors can choose to delete any listings for irrelevant assessments in their To Do list, they tend most often to be infrequent users of Canvas and are thus not aware of these options. https://community.canvaslms.com/t5/Canvas-Admin-Discussion/Permission-limitations-on-custom-roles-ba...

Proposed solution:

Add the option to restrict teachers/tutors to only see/edit/grade assessments that are relevant to them. This could be achieved for example by adding teachers to a section and then specifying that section in the Assign area within the assignment settings screen. As a bonus from adding this option, full time teachers would also be able to opt to reduce the number of reminders they receive about assessments they need to grade.
