Enforcement of mentor groups for queue labs

It should be possible to enforce that students are part of a specific mentor group (letter only e.g. A) for them to be able to sign up for a specific queue. This will prevent students from signing up for labs they are not supposed to be in, and eliminates time TA's spend on manual enforcement of this policy.

• Ideally it should be possible to check boxes for mentor groups per lab session as a manager. This way a subset of the mentor groups can sign-up for specific lab sessions.
• There should also be a status for students that do not have a mentor group (higher year, bridging programme, etc.) as unknown. Students in this group should be able to join any lab by default, or have a separate checkbox like described above.
