Add support for LaunchTemplates in aws-dotnet-deploy tool. LaunchConfigurations are not supported anymore

[chitikjb]

Describe the bug

Starting on October 1, 2024, new accounts will not be able to create new launch configurations by using the console, API, CLI, and CloudFormation. https://docs.aws.amazon.com/autoscaling/ec2/userguide/create-launch-config.html

This created an issue when I used aws-dotnet-deploy tool in my devops pipeline to deploy a .NET 8 webAPI to elastic beanstalk (linux) environment in a brand new AWS account. Currently the tool only supports LaunchConfiguration and not LaunchTemplates, that causes the issue.

Regression Issue

Expected Behavior

The deployment to go smoothly

Current Behavior

The deployment fails because LaunchConfigurations are not supported anymore in new aws accounts and the tool uses LaunchConfigurations in it's autoscaling group for load balanced EB deployments.

Reproduction Steps
