Suspend an auto scaling group's scaling processes that can interfere with CodeDeploy deploys.
It assumes a single ASG per deployment group.

To use this:
* create a lambda function with this code, then hook up it up to an SNS topic that receives all deployment events (but not host events).
* attach that topic as a trigger in your deployment groups.

Unlike AWS's in-appspec approach, this supports arbitrary deploy concurrency.
