Enh/rtmp proxy

[carlobortolan]

Motivation and Context

See #1386.

Description

• Updated token panel that allows lecturers to create new lecturer tokens with additional info for different streaming software/services.
• New API endpoint at /api/token/proxy that can be used by the RTMP Proxy to exchange the lecturer token with a stream-specific URL for an upcoming stream.
• Added test courses that are automatically created under the "TEST COURSES" semester when one starts streaming without having scheduled active or soon starting stream.

Steps for Testing

Prerequisites:

• 1 Lecturer
• 1 RTMP-Proxy (https://github.com/arut/nginx-rtmp-module)

1. Log in.
2. Create a soon-starting stream.
3. Go to the token panel and create a new lecturer token.
4. Follow the instructions on the screen to start self-streaming from OBS via the RTMP-Proxy, or make a manual POST request to http://localhost:8081/api/token/proxy/<your-token> to check if the stream URL is correct.

Note

To change the default settings of the test courses, see:
