Title: Cloud Formation Auto Generated Names and ASG opt in/out

Hi

When using cloud formation, the ASG created has a random string appended, such as:

foo-my-app-MyAutoScalingGroup-1727U49KMHGUT

We are currently using the opt in feature with Chaosmonkey to select a subset of our ASGs for Chaosmonkey to target.

So we put 'simianarmy.chaos.ASG.foo-my-app-MyAutoScalingGroup-1727U49KMHGUT.enabled =1' into the properties file.

However this can be a little problematic as occasionally we update the stack. This creates a new random string as a suffix to the ASG name and causes the opt-in configuration to fail to match the previously matched ASG.

Is there a way we can use some kind of pattern matching and if not could we submit a patch to solve this problem.
