feat: Add the Cluster Autoscaler

[aakilin]

• fix sync-wave inside the application folder
• add IAM module "cluster_autoscaler_irsa_role"
• move the cluster-autoscaler path to kube-system
• inner wave shouldn’t be 30th - make sense to set it 0
• clustername inside the values should be a tokenized by <PRIMARY_CLUSTER_NAME>
• aws-region should be tokenized by <CLOUD_REGION>
• cloud-provider should be tokenized by <CLOUD_PROVIDER>
• service-account should be tokenized by SERVICE_ACCOUNT - create the new one
  <K8S_ROLE_MAPPING>: “<CLUSTER_AUTOSCALER_IAM_ROLE_RN>”
• add the output cluster_autoscaler_role with value = module.hosting-provider.cluster_autoscaler_irsa_role
• add p.parameters["<CLUSTER_AUTOSCALER_IAM_ROLE_RN>"] = hp_out["cluster_autoscaler_role"]
• add the cluster_autoscaler_irsa_role to the terraform cloud_aws module outputs
