// Modifies the specified EC2 Fleet. You can only modify an EC2 Fleet request of
// type maintain . While the EC2 Fleet is being modified, it is in the modifying
// state. To scale up your EC2 Fleet, increase its target capacity. The EC2 Fleet
// launches the additional Spot Instances according to the allocation strategy for
// the EC2 Fleet request. If the allocation strategy is lowest-price , the EC2
// Fleet launches instances using the Spot Instance pool with the lowest price. If
// the allocation strategy is diversified , the EC2 Fleet distributes the instances
// across the Spot Instance pools. If the allocation strategy is capacity-optimized
// , EC2 Fleet launches instances from Spot Instance pools with optimal capacity
// for the number of instances that are launching. To scale down your EC2 Fleet,
// decrease its target capacity. First, the EC2 Fleet cancels any open requests
// that exceed the new target capacity. You can request that the EC2 Fleet
// terminate Spot Instances until the size of the fleet no longer exceeds the new
// target capacity. If the allocation strategy is lowest-price , the EC2 Fleet
// terminates the instances with the highest price per unit. If the allocation
// strategy is capacity-optimized , the EC2 Fleet terminates the instances in the
// Spot Instance pools that have the least available Spot Instance capacity. If the
// allocation strategy is diversified , the EC2 Fleet terminates instances across
// the Spot Instance pools. Alternatively, you can request that the EC2 Fleet keep
// the fleet at its current size, but not replace any Spot Instances that are
// interrupted or that you terminate manually. If you are finished with your EC2
// Fleet for now, but will use it again later, you can set the target capacity to
// 0.
