IMDSv2: AutoscalingGroups should support LaunchTemplate instead of/as well as LaunchConfiguration

[winjer]

Support LaunchTemplates as part of AutoScalingGroups as well as or instead of LaunchConfigurations.

Use Case

I am required to use IMDSv2 by our security policy.

From the docs:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html:

To require the use of IMDSv2 on all new instances launched by Auto Scaling groups, your Auto Scaling groups must use launch templates. When you create a launch template, configure the MetadataOptions parameters to require the use IMDSv2. For Auto Scaling groups that use launch configurations, replace the launch configurations with launch templates.

Proposed Solution

@aws-cdk/aws-autoscaling needs changing.
