Tag EBS volumes created by autoscaling.

Currently there is no way for EC2 autoscaling to tag EBS volumes when they are created. The ebsautotagger lambda function will automatically add tags to EBS volumes as autoscaling launches the instances. A Cloudwatch Events rule is used to invoke the lambda. It will tag all non-root EBS volume with the tags you specify in the lambda function.

You will most certainly need to adjust the lambda function to meet your needs. The example function will add a few sample tags. It looks for an instance tag called service with a value defined in the environment variable SERVICE_TAG_VALUE. You will want to adjust this for your environment or replace it with something that makes more sense for you.

The terraform directory contains terraform code that sets everything up. This terraform will do the following:

1. Deploy lambda function
2. Create Cloudwatch Rule that invokes the lambda function when autoscaling launches instances.
3. Create all the required IAM permissions
