Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) database calls.
• I followed the coding and design guidelines.
• I added multiple integration tests (Spring) related to the features (with a high test coverage).
• I added pre-authorization annotations according to the guidelines and checked the course groups for all new REST Calls (security).
• I documented the Java code using JavaDoc style.

Client

• Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data.
• I followed the coding and design guidelines.
• Following the theming guidelines, I specified colors only in the theming variable files and checked that the changes look consistent in both the light and the dark theme.
• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I added authorities to all new routes and checked the course groups for displaying navigation elements (links, buttons).

Motivation and Context

Currently, if an instructor wants to have a high variance of quiz questions for an exam, the instructor needs to create a huge number of quiz exercises. Quiz Pool is created to improve the user experience for instructors to prepare such requirements by having groups of quiz questions that will be randomly selected for each student exam.

Description

1. Add a new component QuizPoolMappingComponent to enable the instructor to map quiz questions to groups.
2. Add a new Quiz Pool Configuration page that uses the QuizPoolMappingComponent and QuizQuestionEditListComponent.
3. Add a Quiz Pool button to the Exam Detail Page
4. Add a new entity: QuizPool and QuizGroup.
5. Add the relationships between Exam, QuizQuestion, QuizGroup, and QuizPool.
6. Add Quiz Pool API to update and retrieve Quiz Pool Configuration.
7. Add quiz_pool and quiz_group Tables.
8. Add the relationships between exam, quiz_pool, quiz_question, and quiz_group Tables.

This is the class diagram that represents the changes. The classes and the lines with green color mean the classes and the relationships are added on this PR.
