// Modifies the placement attributes for a specified instance. You can do the
// following:
//   - Modify the affinity between an instance and a Dedicated Host (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/dedicated-hosts-overview.html)
//     . When affinity is set to host and the instance is not associated with a
//     specific Dedicated Host, the next time the instance is launched, it is
//     automatically associated with the host on which it lands. If the instance is
//     restarted or rebooted, this relationship persists.
//   - Change the Dedicated Host with which an instance is associated.
//   - Change the instance tenancy of an instance.
//   - Move an instance to or from a placement group (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html)
//     .
//
// At least one attribute for affinity, host ID, tenancy, or placement group name
// must be specified in the request. Affinity and tenancy can be modified in the
// same request. To modify the host ID, tenancy, placement group, or partition for
// an instance, the instance must be in the stopped state.
