	//   - 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

	//   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.

	//   - submitted - The EC2 Fleet or Spot Fleet request is being evaluated and

	//   capacity of the fleet was modified down, for example, from a target capacity of
	//   4 to a target capacity of 3.
