- This enables us to use a scope to query all clusters in group hierarchy order in one query, and also enables us to union to instance clusters later. - Handle case where clusters not present at level. In which case the query should go ahead and return the next level's clusters. - Swap with new CTE query behind Feature flag. This FF is default disabled.
