[Request for Implementation] JupyterHub aware kubernetes cluster autoscaler

But you’d have to reduce the number of placeholder pods again once the class has “started” which might be tricky to know/automate.

Once you’ve built a UI or API for setting the number of placeholders in the hub you could automate it by creating a hub service that runs every minute and:

1. counts the number of user pods
2. sets number_of_placeholders = expected_class_size - current_number_of_users
