Virtual staff-in-the-lab whiteboard

[Milotrince]

Some mechanism for listing where staff are in the lab for opstaff to reference that doesn't rely on being logged in on desktops (since staff tend not to do that 🙃)

[oski-bear]

Temporary thrown-together measure: Make staff ssh into tsunami or a desktop when in the lab to make wittl work properly in this case. We can create a more permanent solution and move this to a yaml file in etc when we have the time.
