Configure Terraform variables

Create a .auto.tfvars file with the following:
- region - the AWS region where resources will be deployed. Must be one of the HCP supported regions for the HCP Consul servers.
- lb_ingress_ips - Your IP. This is used in the load balancer security groups to ensure only you can access the demo application.
- suffix - a suffix appended to the name of created resources
For example,
```
$ cat .auto.tfvars
region         = "us-east-1"
lb_ingress_ips = ["<your-ip>/32"]
suffix         = "demo"
```
Run terraform
```
terraform init
terraform apply
```

(optional) Configure kubectl

aws eks --region $(terraform output -raw region) update-kubeconfig --name $(terraform output -raw local.eks_cluster_name)
kubectl get pods -A
