[FEAT] Support attaching NLB server groups to Auto Scaling groups in the Alicloud Terraform Provider

[Auditore8]

Description

The current AliCloud Auto Scaling Terraform module does not support attaching NLB (Network Load Balancer) server groups to the auto-scaling group. While both the AliCloud Console and OpenAPI support attaching NLB server groups, this functionality is not available in the Terraform module.While users can manually perform this action in the Alibaba Cloud console, the lack of support in Terraform makes it difficult to maintain configuration consistency and automation.

Aspect

• Auto Scaling
• NLB

Details

Current Support:

• The AliCloud Console and OpenAPI both support attaching NLB server groups to auto-scaling groups. For reference, see the AttachServerGroups - Auto Scaling - Alibaba Cloud Documentation Center.

• Currently, the Terraform module only supports attaching ALB (Application Load Balancer) and SLB (Server Load Balancer) server groups.
  • ALB: ess_alb_server_group_attachment
  • SLB: ess_scalinggroup_vserver_groups

Future Support:

• According to feedback from AliCloud support, the function to attach NLB server groups is still under planning.
  Here's the GitHub issue using the provided template based on the information given:

Expected Behavior

The Terraform module should support attaching NLB (Network Load Balancer) server groups to auto-scaling groups, similar to the support for ALB (Application Load Balancer) and SLB (Server Load Balancer) server groups.

Actual Behavior

The current AliCloud Auto Scaling Terraform module does not support attaching NLB server groups. Users can manually perform this action in the Alibaba Cloud console, but the lack of support in Terraform makes it difficult to maintain configuration consistency and automation.

Steps to Reproduce

1. Create an auto-scaling group using the Terraform configuration above.
2. Attempt to attach an NLB server group to the auto-scaling group (currently not supported).
