Yusuke Kuoka dfb481b19f cluster-autoscaler: Fix excessive calls to DescribeAutoScalingGroup
By caching AWS refs for nodes/EC2 instances already known to be not in any of ASGs managed by cluster-autoscaler(CA).

Please beware of the edge case - this method is safe as long as users don't attach nodes by calling AttachInstances API after CA cached them. I believe, even if it was necessary, a warning in the documentation about the edge case is enough for now. If we really need to support the case, I will submit an another PR to invalidate the cache periodically so that CA can detect the formerly cached nodes are attached to ASG(s).

Also refactor AwsManager for less complexity by extracting types, accordingly to the discussion made [here](https://github.com/kubernetes/autoscaler/pull/46#discussion_r117912687)
