Subject: [PATCH] Enable ECS Cluster autoscaling group metrics

* Adds the list of enabled metrics for the ECS Cluster's autoscaling
  group. These are the metrics that are automatically enabled when
  choosing to enable metrics within the AWS console, which is also the
  full list of metrics avaiable for the autoscaling group.
