Sane Defaults for Agents

This release sets sane defaults to the Consul and Regisratror agents, well saner then it was before :) This release also updates deployment_minimum_healthy_percent to allow for smoother redeployments of the agents. See here for more info https://docs.aws.amazon.com/AmazonECS/latest/developerguide/service_definition_parameters.html

Autoscaling Group names now use name_prefix

Autoscaling Group names now use name_prefix, which makes generating unique ASG groups more reliable, but also causes the entire ASG to be torn down and rebuild. This also address the create before destroy bug. Details in #20 and hashicorp/terraform-provider-aws#1730

Adds min_servers and max_servers variables

Allow people to set min_servers and max_servers variables

Replaces IAM names with name_prefix

This release is a breaking release that will destroy and recreate your the names of your IAM resources, causing the cluster to be rebuilt. This release however does make IAM resources globally unique which is useful when creating clusters in multiple regions with the same name

Adds iam_path argument to IAM Resources

Adds the option to define custum IAM paths, i.e. iam_path = "/tf/${var.region}/", which is useful when creating IAM resources in
the same account across multiple regions, using the same name. So for
example if you have a ECS Cluster in us-east-1 and us-east-2 both name "dev"

Adds Consul and Registrator agents to ECS Instances

• Adds Consul and Registrator agents to ECS Instances
