	//
	//   - spotFleetRequestConfigurationInvalid - The configuration is not valid. For
	//   more information, see the description of the event.
	//
	// fleetRequestChange events:
	//
	//   - active - The EC2 Fleet or Spot Fleet request has been validated and Amazon
	//   EC2 is attempting to maintain the target number of running instances.
	//
	//   - deleted (EC2 Fleet) / cancelled (Spot Fleet) - The EC2 Fleet is deleted or
	//   the Spot Fleet request is canceled and has no running instances. The EC2 Fleet
	//   or Spot Fleet will be deleted two days after its instances are terminated.
	//
	//   - deleted_running (EC2 Fleet) / cancelled_running (Spot Fleet) - The EC2 Fleet
	//   is deleted or the Spot Fleet request is canceled and does not launch additional
	//   instances. Its existing instances continue to run until they are interrupted or
	//   terminated. The request remains in this state until all instances are
	//   interrupted or terminated.
	//
	//   - deleted_terminating (EC2 Fleet) / cancelled_terminating (Spot Fleet) - The
	//   EC2 Fleet is deleted or the Spot Fleet request is canceled and its instances are
	//   terminating. The request remains in this state until all instances are
	//   terminated.
	//
	//   - expired - The EC2 Fleet or Spot Fleet request has expired. If the request
	//   was created with TerminateInstancesWithExpiration set, a subsequent terminated
	//   event indicates that the instances are terminated.
	//
	//   - modify_in_progress - The EC2 Fleet or Spot Fleet request is being modified.
	//   The request remains in this state until the modification is fully processed.
	//
	//   - modify_succeeded - The EC2 Fleet or Spot Fleet request was modified.
	//
	//   - submitted - The EC2 Fleet or Spot Fleet request is being evaluated and
	//   Amazon EC2 is preparing to launch the target number of instances.
	//
	//   - progress - The EC2 Fleet or Spot Fleet request is in the process of being
	//   fulfilled.
	//
	// instanceChange events:
	//
	//   - launched - A new instance was launched.
	//
	//   - terminated - An instance was terminated by the user.
	//
	//   - termination_notified - An instance termination notification was sent when a
	//   Spot Instance was terminated by Amazon EC2 during scale-down, when the target
	//   capacity of the fleet was modified down, for example, from a target capacity of
	//   4 to a target capacity of 3.
	//
	// Information events:
	//
	//   - fleetProgressHalted - The price in every launch specification is not valid
	//   because it is below the Spot price (all the launch specifications have produced
	//   launchSpecUnusable events). A launch specification might become valid if the
	//   Spot price changes.
	//

	//   description of the event.
	//
	//   - launchSpecUnusable - The price specified in a launch specification is not

	//
	// Note: Even if a fleet with the maintain request type is in the process of being
	//   canceled, it may still publish a launchSpecUnusable event. This does not mean
