Autoscaling Groups - Auto Recovery

[benofben]

AWS Autoscaling groups don't handle failures well. At some point, we should automate recovery. Until then recovery can be done manually.

"When your instance is terminated, any associated Elastic IP addresses are disassociated and are not automatically associated with the new instance. You must associate these Elastic IP addresses with the new instance manually. Similarly, when your instance is terminated, its attached EBS volumes are detached. You must attach these EBS volumes to the new instance manually."

I think we need to allow some method is disable autoscaling groups.
