Description

Currently, getMaxHeadRoom() returns nil when capacity is not set, we expect this queue has unlimited capacity; however, resources.FitIn(headRoom, request.AllocatedResource) will always return false in such case
this causes the problem if the queue has no capacity set, pods will not be set to unschedulable to trigger auto-scaling (we expect this is always setting to unschedulable)
