[storage] Add 'query' interface
'query' interface and 'dataNode.accept' constitute an implementation
of 'Visitor' desing pattern. There is going to be a large pool of SQL
queries for both loading and saving data.
'dataNode' object is inspired by 'Composite' pattern, but they don't
allow general 'Iterator' pattern, since all 'queries' require specific
iteration to match underlying SQL.
