    Provides an Auto Scaling Attachment resource.

    NOTE on Auto Scaling Groups and ASG Attachments: This provider currently provides both a standalone aws.autoscaling.Attachment resource (describing an ASG attached to an ELB or ALB), and an aws.autoscaling.Group with load_balancers and target_group_arns defined in-line. These two methods are not mutually-exclusive. If aws.autoscaling.Attachment resources are used, either alone or with inline load_balancers or target_group_arns, the aws.autoscaling.Group resource must be configured to ignore changes to the load_balancers and target_group_arns arguments.
