{
  "control": {
    "accounts": [
      {
        "name": "Control Account",
        "value": "123456789012"
      }
    ],
    "roles": [
      {
        "name": "Deploy Admin",
        "value": "deployment/admin"
      },
      {
        "name": "Super Admin",
        "value": "security/admin"
      },
      {
        "name": "Read Only",
        "value": "read/only"
      }
    ]
  },
  "target": {
    "roles": [
      {
        "name": "Deploy Admin",
        "value": "deployment/admin"
      },
      {

      }
    ],
    "accounts": [
