Display started labs in lab list command

[ttafsir]

How would you like to improve the project?
Display a visual indicator to show which lab is started when I list all labs. The API allows you to start any lab, even when the GUI restricts starting only one lab at a time. This seems to cause issues with stopping and starting nodes. The start and stop commands are still accepted but are ineffectual.

Describe the solution you'd like
At a minimum, it'd be helpful to see which labs have any running nodes at the CLI before attempting to start another. This could help inform you to stop one lab before starting the other.

Describe alternatives you've considered
NA
