Synchronization of instructors and TAs with Canvas

• need to sync instructors and TAs

[wynnset]

When creating a course based on a Canvas course:

Import Instructors:

• Import with "instructor" system role
• Assign as instructor for the course

Import TAs:

• Import with "student" system role
• Assign as instructor for the course

Before starting on this, ensure the method above will work for imported TAs:

• Ensure TA will be able to see everything within the assigned course (same as instructor)
• Ensure TA cannot create a course or do other admin functionality.

With system role as student and course role as instructor, the user can't access the /courses page. Thus the user can't create events or manage groups. Also, this kind of role setup is not support by the current users page. @xcompass Either we need to revise the current logic or introduce a new TA role.
