Additional support for Terraform v0.13 and aws v3! - The update to the vpc module in examples was, strictly speaking, unnecessary but it adds the terraform block with supported versions. - Update for iam module in the example was very necessary to support new versions - Workaround for "Provider produced inconsistent final plan" when creating ASGs at the same time as the cluster. See https://github.com/terraform-providers/terraform-provider-aws/issues/14085 for full details. - Blacklist 0.13.0 as it was too strict when migrating from aws v2 to v3 about dropped attributes.
