BREAKING(aws-ec2): move AutoScalingGroup (#608)
This construct should have been in the @aws-cdk/aws-autoscaling package, as that is the CloudFormation namespace name. This will also help avoid a dependency cycle pending in another PR, where we want to add a dependency from aws-lambda => aws-ec2.

| ## The CDK Construct Library for AWS Auto-Scaling | ||
| This module is part of the [AWS Cloud Development Kit](https://github.com/awslabs/aws-cdk) project. | ||
|
|
||
| ### Fleet | ||
|
|
||
| ### Auto Scaling Group | ||
|
|
||
| An `AutoScalingGroup` represents a number of instances on which you run your code. You | ||
| pick the size of the fleet, the instance type and the OS image: | ||
|
|
||
| ```ts | ||
| import ec2 = require('@aws-cdk/aws-ec2'); | ||
|
|
||
| new ec2.AutoScalingGroup(stack, 'ASG', { | ||
| vpc, | ||
| instanceType: new ec2.InstanceTypePair(InstanceClass.Burstable2, InstanceSize.Micro), | ||
| machineImage: new ec2.LinuxImage({ | ||
| 'us-east-1': 'ami-97785bed' | ||
| }) | ||
| }); | ||
| ``` | ||
|
|
||
| > NOTE: AutoScalingGroup has an property called `allowAllOutbound` (allowing the instances to contact the | ||
| > internet) which is set to `true` by default. Be sure to set this to `false` if you don't want | ||
| > your instances to be able to start arbitrary connections. | ||
| ### AMIs | ||
|
|
||
| AMIs control the OS that gets launched when you start your instance. | ||
|
|
||
| Depending on the type of AMI, you select it a different way. | ||
|
|
||
| The latest version of Windows images are regionally published under labels, | ||
| so you can select Windows images like this: | ||
|
|
||
| new ec2.WindowsImage(WindowsVersion.WindowsServer2016EnglishNanoBase) | ||
|
|
||
| You can select the latest Amazon Linux image like this: | ||
|
|
||
| new ec2.AmazonLinuxImage() | ||
|
|
||
| Other Linux images are unfortunately not currently published this way, so you have | ||
| to supply a region-to-AMI map when creating a Linux image: | ||
|
|
||
| machineImage: new ec2.GenericLinuxImage({ | ||
| 'us-east-1': 'ami-97785bed', | ||
| 'eu-west-1': 'ami-12345678', | ||
| // ... | ||
| }) | ||
|
|
||
| > NOTE: Selecting Linux images will change when the information is published in an automatically | ||
| > consumable way. | ||
| ### Allowing Connections | ||
|
|
||
| See the documentation of the aws-ec2 package for more information about allowing | ||
| connections between resources backed by instances. |
