What should happen to connected workers that have just been disabled

Situation:

• worker-xxx is approved and is connected to the Debusine server
• Debusine admin does debusine-admin manage_worker disable worker-xxx

What happens (I haven't tested it but we don't have any code to prevent this):

• Worker remains connected and will keep receiving work requests (we check the token status on connection only)
• The next time that the worker connects it will be rejected

Questions:

• Should the debusine server disconnect the worker if its token gets disabled?
• Is this part of milestone 1? (I've assigned it to milestone 1 to keep track of this while we decide)
