// Modifies the specified Spot Fleet request. You can only modify a Spot Fleet
// request of type maintain . While the Spot Fleet request is being modified, it is
// in the modifying state. To scale up your Spot Fleet, increase its target
// capacity. The Spot Fleet launches the additional Spot Instances according to the
// allocation strategy for the Spot Fleet request. If the allocation strategy is
// lowestPrice , the Spot Fleet launches instances using the Spot Instance pool
// with the lowest price. If the allocation strategy is diversified , the Spot
// Fleet distributes the instances across the Spot Instance pools. If the
// allocation strategy is capacityOptimized , Spot Fleet launches instances from
// Spot Instance pools with optimal capacity for the number of instances that are
// launching. To scale down your Spot Fleet, decrease its target capacity. First,
// the Spot Fleet cancels any open requests that exceed the new target capacity.
// You can request that the Spot Fleet terminate Spot Instances until the size of
// the fleet no longer exceeds the new target capacity. If the allocation strategy
// is lowestPrice , the Spot Fleet terminates the instances with the highest price
// per unit. If the allocation strategy is capacityOptimized , the Spot Fleet
// terminates the instances in the Spot Instance pools that have the least
// available Spot Instance capacity. If the allocation strategy is diversified ,
// the Spot Fleet terminates instances across the Spot Instance pools.
// Alternatively, you can request that the Spot 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 Spot Fleet for now, but will
// use it again later, you can set the target capacity to 0.
