deleteFleet
Deletes all resources and information related a fleet. Any current fleet instances, including those in remote locations, are shut down. You don't need to call DeleteFleetLocations separately.
If the fleet being deleted has a VPC peering connection, you first need to get a valid authorization (good for 24 hours) by calling CreateVpcPeeringAuthorization. You do not need to explicitly delete the VPC peering connection.
To delete a fleet, specify the fleet ID to be terminated. During the deletion process the fleet status is changed to DELETING. When completed, the status switches to TERMINATED and the fleet event FLEET_DELETED is sent.
