// Creates a placement group in which to launch instances. The strategy of the
// placement group determines how the instances are organized within the group. A
// cluster placement group is a logical grouping of instances within a single
// Availability Zone that benefit from low network latency, high network
// throughput. A spread placement group places instances on distinct hardware. A
// partition placement group places groups of instances in different partitions,
// where instances in one partition do not share the same hardware with instances
// in another partition. For more information, see Placement groups (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html)
