CP3108 Staff Dashboard - Avengers Leaderboard

[Wong-ZZ]

Context

This PR adds the Avengers Leaderboard component for the CP3108 Staff Dashboard project. The Avengers Leaderboard keeps track of the grading progress of each avenger in the course and displays the total number of ungraded/submitted missions/quest of each avenger

Implementation

• The Avengers Leaderboard is accessible through the Dashboard tab in the navigation bar and can only be accessed by staffs/admin.
• Added a new request method to fetch the overview of all the groups. The overview contains the group id, group name and the name of the the group's avenger.
• Added a new redux state to store the group overviews

The UI for the Avengers Leaderboard can be seen here:

Can you put the description above into a wiki page in cadet frontend?

[Wong-ZZ]

I have added the information for the Avengers Leaderboard in the wiki page. I will also be updating the other parts of the wiki page overtime since we are still making some changes to the components.

On top of that, I have made another commit that contains the tests for the Avengers Leaderboard.
