Description

[Provide a brief description of the changes in this PR]

Enable NLB Sticky Sessions.

Reference

• HashiCorp Terraform Enterprise documentation

  Depending on your infrastructure and Terraform Enterprise configuration, you may need to configure your application gateway or load balancer for sticky sessions. Sticky session refers to the practice of using a load balancer or gateway device with a specific setting enabled that ensures traffic is routed back to the original system that initiated a request. For example, an Active/Active deployment on Azure with SAML authentication requires sticky sessions to ensure the authentication with the SAML server is successful. The terminology for this varies across clouds. Refer to the documentation for your infrastructure.”

• Terraform AWS Provider: aws_lb_target_group

  • NLB Target Group type only supports source_ip as of today
