Grades API

Copied from PR comment.

Grades Courses Resource

This is based on our current API conventions and how other existing edX APIs are designed.

/grades/v1/courses/              Courses grades for all users for all courses
  ?course_id={}&username={}        Course grade for filtered user(s) in filtered course(s)
  ?course_id={}                    Course grades for all users in filtered course(s)
  ?username={}                     Course grades for filtered user(s) in all their courses

/grades/v1/courses/{course_id}  Course grades for all users for a course
  ?username={}                     Course grade for filtered user(s) in a course

...

Grades Users Resource

This is based on the desired need for a user-specific endpoint. We don't currently use this design pattern elsewhere in our system (other than for the user API itself). However, I do see us possibly supporting this pattern (in the future) for certain APIs to allow users and apps to easily get user-specific data without using a filtering API.

/grades/v1/users/me/courses        Course grades for authenticated user in all her courses

/grades/v1/users/{user_id}/courses Course grades for a user in all her courses
  ?course_id={}                      Course grades for a user in filtered course(s)

...

Grades Policy Resource

This is similar to the v0 Grades policy API, but follows the URI RFC by putting the course_id resource under a proper hierarchical container (courses).

/grades/v1/policy/courses/            Grading policy for all courses
  ?course_id={}                         Grading policy for filtered course(s)

/grades/v1/policy/courses/{course_id} Grading policy for a course
