Skip nodes in min-sized groups in scale-down simulation
...
Currently we track if those nodes can be removed and only
skip them at the execution step. Since checking if node is
unneeded is pretty expensive it's better to filter them out
early.

cluster-autoscaler: Re: AWS Autoscaler autodiscover ASG names and sizes
...
This is an alternative implementation of https://github.com/kubernetes/contrib/pull/1982
Notable differences from the original PR are:
* A new flag named `--node-group-auto-discovery` is introduced for opting in to enable the auto-discovery feature.
* For example, specifying `--cloud-provider aws --node-group-auto-discovery asg:tag=k8s.io/cluster-autoscaler/enabled` instructs CA to auto-discover ASGs tagged with `k8s.io/cluster-autoscaler/enabled` to be used as target node groups
* The new code path introduced by this PR is executed only when `node-group-auto-discovery` is specified. There is relatively less chance to break existing features by introducing this change
Resolves https://github.com/kubernetes/contrib/issues/1956
---
Other notes:
* We rely mainly on the `DescribeTags` API rather than `DescribeAutoScalingGroups` so that AWS can filter out unnecessary ASGs which doesn't belong to the k8s cluster, for us.
* If we relied on `DescribeAutoScalingGroups` here, as it doesn't support `Filter`ing, we'd need to iterate over ALL the ASGs available in an AWS account, which isn't desirable due to unnecessary excessive API calls and network usages
* Update cloudprovider/aws/README for the new configuration
* Warn abount invalid combination of flags
according to the review comment https://github.com/kubernetes/autoscaler/pull/11#discussion_r113713138
* Emit a validation error when both --nodes and --node-group-auto-discovery are specified
according to the review comment https://github.com/kubernetes/autoscaler/pull/11#discussion_r113958080
TODO/Possible future improvements before recommending this to everyone:
* Cache the result of an auto-discovery for a configurable period, so that we won't invoke DescribeTags and DescribeAutoScalingGroup APIs too many times
