Add /assignment endpoints in course-management

[benjaminkostiuk]

Overview

Implement the /assignment endpoints defined in the API planning document https://github.com/puffproject/docs/blob/master/API_ARCHITECTURE.md.

You can break the following into separate issues for pull requests if you want.

Breakdown

1. Create an Assignment entity based on the ASSIGNMENT table.

• Should have a many to one mapping to courses.
• Can maybe include both the Course object and id as separate fields if that makes things easier.

2. Create an AssignmnentAttribute entity based on the ASSIGNMENT_ATTR table.

• Should be similar to the CourseAttribute entity.
• You'll also need an Enum for the attribute names.

2.5. Create AssignmentPage and AssignmentAttributeView models.

• You can do this by extending BasePage and AssignmentAttributeView will have the same fields as values for the enum from 2.

3. Create a Assignment & AssignmentAttribute JPA repository interfaces.

• Similar to the Course repositories already created.

4. Create an Assignment service interface and class

• Should be similar to the CourseService already implemented
• Don't forget to throw ElementNotFound exceptions if the associated Course can't be found for an assignment.

5. Create an REST interface for Assignment endpoints

• Similar to the Course REST interface already created.

6. Implement the REST interface with a RestController for Assignment endpoints

• Similar to the Course Controller.
• Don't forget the security and access control on endpoints.

7. Write tests for your endpoints (You should also test manually)

• Unit tests for your Assignment service class
• Api component tests for your new apis
• There are already some tests written for Courses that you can work off of.

@jeevanauluck I think this could be a good first issue to start on. Try breaking it up into a few separate pull requests. The structure is going to be similar to the Course endpoints.

The creation of JPA Assignment & AssignmentAttribute JPA repositories is blocking #2, so for now to unblock going to allow @youcefs21 to implement them. We can refactor as needed later.
