Add the creation of the service and auto scaling to the template

It seems odd to have a cloud formation template and then tell the user to set up a few things by hand, can steps 3,4 and 5 not be part of the template? I came across this trying to find an example of adding the auto scaling to the ecs service in a template.

Review the repository's CloudFormation template and the manual setup steps 3, 4, and 5 described in the project documentation. Compare those steps with the requested ECS service and auto scaling configuration; done means the relevant setup is represented in the template so users no longer need to perform it by hand.
