NOTES: Set an ASG's launch template version to an explicit version automatically. This will ensure that an instance refresh will be triggered whenever the launch template changes. The default `launch_template_version` is now used to determine the latest or default version of the created launch template for self-managed worker groups.

BREAKING CHANGES: This module used `random_pet` resources to create a random name for the autoscaling group to force the autoscaling group to be re-created when the launch configuration or launch template was changed (if `recreate_asg_when_lc_changes = true` was set), causing the instances to be removed and re-provisioned each time there was an update. Those random_pet resources has been removed and in its place there is now a set of functionality provided by AWS and the Terraform AWS provider - Instance Refresh. We encourage those users to move on Instance Refresh for EC2 Auto Scaling.
BREAKING CHANGES: We remove the dependency on the deprecated `hashicorp/template` provider and use the Terraform built in `templatefile` function. This will broke some workflows due to previously being able to pass in the raw contents of a template file for processing. The `templatefile` function requires a template file that exists before running a plan.
NOTES: Using the [terraform-aws-modules/http](https://registry.terraform.io/providers/terraform-aws-modules/http/latest) provider is a more platform agnostic way to wait for the cluster availability than using a local-exec. With this change we're able to provision EKS clusters and manage the `aws_auth` configmap while still using the `hashicorp/tfc-agent` docker image.
BREAKING CHANGES: To add add SPOT support for MNG, the `instance_type` is now a list and renamed as `instance_types`. This will probably rebuild existing Managed Node Groups.
NOTES: The EKS cluster can be provisioned with both private and public subnets. But Fargate only accepts private ones. This new variable allows to override the subnets to explicitly pass the private subnets to Fargate and work around that issue.
