> For Legacy SQL, BigQuery Operator/Hook flattens the repeated column. The underlying Google
Query JSON API's parameter "flattenResult" has default value of false, by not setting it every
Legacy SQL result is flattened. 
> Without this config option, Legacy SQL can't be used for queries with repeated columns.
 Even though it looks like feature request, I consider this as a bug as this config option
should have been in the first place.
> I am working on submitting PR to github project.
