   Hi,
   
   We are currently having some issues with SQL Lab permissions related to 
tables appearing in subselects.
   
   Our Superset users have datasource permissions that are evaluated when the 
execute a query in SQL Lab.
   Sql Lab uses the 
[ParsedQuery](https://github.com/apache/superset/blob/383313b105b0e82bea0f38cc971630eded5affe0/superset/sql_parse.py#L189)
 class to extract the tables on that query and then evaluates if a user can 
actually execute the query based on those permissions.
   
   Since 
[ParsedQuery](https://github.com/apache/superset/blob/383313b105b0e82bea0f38cc971630eded5affe0/superset/sql_parse.py#L335)
 excludes subselects from the table parsing mechanism, a user could hide a 
particular table that he/she doesn't have access to inside a subquery and get 
away with that.
   
   Our idea is to modify the ParsedQuery logic to actually include, or at least 
give the option to include, the subqueries when retrieving the tables involved 
in a query, would that be something sensible?
