scalingAdjustment property
The amount by which to scale in or scale out, based on the specified
AdjustmentType. A positive value adds to the instance group's
EC2 instance count while a negative number removes instances. If
AdjustmentType is set to EXACT_CAPACITY, the
number should only be a positive integer. If AdjustmentType is
set to PERCENT_CHANGE_IN_CAPACITY, the value should express the
percentage as an integer. For example, -20 indicates a decrease in 20%
increments of cluster capacity.
