Introduce a utility function to issue a basic LiveKit access token with the minimal
required video grants for videoconferencing.
/!\ This function is naive, and doesn’t handle properly all cases. It’s under construction.
Testing was conducted using the LiveKit connection test tool https://livekit.io/connection-test,
which allows users to input the address of their local LiveKit server and an access token.
** Upcoming improvements? **
- Unit tests should be added.
- User display name should be their full name instead of their email address.
- Anonymous users should be allowed to provide a full name when requesting access to the room.
- Video grants should be adapted based on the room configuration and the user's role.
These improvements will be addressed in future commits.
Nevertheless, with this draft, we should be able to address various situations, including
public rooms, permanent rooms, temporary rooms, logged-in users, and anonymous users.
