[Enhancement]: Implementing the Termination Hook in CodeDeploy's deployment environment

[shblue21]

Description

Hello, last month the CodeDeploy AutoScaling Termination Hook feature was released and I would like to implement it.
Previously, autoscaling would crash the application when a scale-in event occurred (as the instance was shut down).
With Hooks, you can now use CodeDeploy's LifeCycle flow to shut down your application normally.

Affected Resource(s) and/or Data Source(s)

• aws_codedeploy_deployment_group

Potential Terraform Configuration

resource "aws_codedeploy_deployment_group" "example" {
  app_name              = aws_codedeploy_app.example.name
  deployment_group_name = "example-group"
  service_role_arn      = aws_iam_role.example.arn
  autoscaling_groups = "deploy-asg"

...
  termination_hook_enabled = true
...

}

Is the PR planned to be merged? This feature has been GA for 9 months and there's no way to manage it in tf

@Jeff-SearchPilot I haven't received any feedback from reviewers since adding this feature, so I'll double check. The Termination Hook is quite useful.
