Communication: Allow tutors to monitor channels as moderator

[cremertim]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• I chose a title conforming to the naming conventions for pull requests.

Server

• Important: I implemented the changes with a very good performance and prevented too many (unnecessary) and too complex database calls.
• I strictly followed the server coding and design guidelines.

Client

• I added multiple integration tests (Jest) related to the features (with a high test coverage), while following the test guidelines.
• I added multiple screenshots/screencasts of my UI changes.

Motivation and Context

Currently, tutors are not able to monitor chats without the cumbersome work of granting each tutor for each channel moderation rights. This affects teaching, since instructors cannot monitor every channel on their own with potentially over 2000 students asking questions

Description

I allowed tutors to pin, delete post and answer posts, if they are not an announcement.

Steps for Testing

Prerequisites:

• 1 Tutor
• 1 Instructor

1. Log in to Artemis
2. Navigate to Course Overview
3. Try to delete an post and an answer to this post from a different user as tutor and instructor (should be possible)
4. Try to delete an announcement as tutor (should not be possible) and as instructor (should be possible)
