max_spin_up_time_min
- the maximum time for an instance to spin upmax_idle_time_min
- the maximum time for an instance to stay up with worker on it (the time the ec2 instance is finished running a task with the agent and still up with an worker running on it listening to the queue)
AFAIK max spinup time is max life of agent (busy or idle) and max idle is maximum allowed time to be idle
