Ember-data override to pull out meta data from a particular data type. Note this is a findAll override. So we're pulling back a collection of locations.

normalizeFindAllResponse(store, primaryModelClass, payload, id, requestType) {
  if (primaryModelClass.modelName === 'location') { // My data model in this case is location.
    if (payload && payload.hasOwnProperty('meta')) {
      let meta = payload.meta;
      //Store / persist or do something your meta data.
      delete payload.meta;
    }
  }
  return this._super(...arguments);
}
