Nested Locales w/ Nested Roles

Nested Locales with Nested Roles

Nested roles needs to work with nested locales

A locale can have a role defined on the locale template or object. If a user
has the role they have access to the locale.

In that locale there are multiple locales that we can merge into. These locales
also have a role defined on their templates/objects, where if a user has the
relevant role they will have access to the nested locale.

-- Workspace

{
  "locales": {
    "germany": {
      "template": "germany_template",
      "locales": ["globalvista_template"]
    },
    "uk": {
      "template": "uk_template",
      "locales": ["globalvista_template", "coremarkets_template"]
    }
  }
}

-- Germany Template

{
  "role": "germany",
  "layers": {
    "OSM_GERMANY": {
      "display": true,
      "format": "tiles",
      "URI": "https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png",
      "attribution": {
        "© OpenStreetMap": "http://www.openstreetmap.org/copyright"
      }
    }
  }
}

-- GlobalVista Template

{
  "role": "globalvista",
  "layers": {
    "OSM_GLOBALVISTA": {
      "display": true,
      "format": "tiles",
      "URI": "https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png",
      "attribution": {
        "© OpenStreetMap": "http://www.openstreetmap.org/copyright"
      }
    }
  },
  "locales": ["brand_a_template", "brand_b_template"]
}

-- brand a

{
  "role": "brand_a",
  "layers": {
    "OSM_BRAND_A": {
      "display": true,
      "format": "tiles",
      "URI": "https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png",
      "attribution": {
        "© OpenStreetMap": "http://www.openstreetmap.org/copyright"
      }
    }
  }
}

We expect the roles returned from the workspace to be

{
  "roles": [
    "germany",
    "globalvista",
    "brand_a",
    "germany.globalvista",
    "germany.globalvista.brand_a"
  ]
}
