add capability to use allfields sql notation

in a dto, this PR allow to call u.* to get all fileds fo u entity in one call,

docs/en/reference/dql-doctrine-query-language.rst

@@ -674,6 +674,17 @@ The ``NAMED`` keyword must precede all DTO you want to instantiate :
 If two arguments have the same name, a ``DuplicateFieldException`` is thrown.
 If a field cannot be matched with a property name, a ``NoMatchingPropertyException`` is thrown. This typically happens when using functions without aliasing them.
 
+In a Dto, if you want add all fields of an entity, you can use AllFields notation :
+.. code-block:: php
+
+    <?php
+    $query = $em->createQuery('SELECT NEW NAMED CustomerDTO(c.name, NEW NAMED AddressDTO(a.*) AS address) FROM Customer c JOIN c.address a');
+    $users = $query->getResult(); // array of CustomerDTO
+
+    // CustomerDTO => {name : 'DOE', email: null, city: null, address: {id: 18, city: 'New York', zip: '10011'}}
+
+It's recommended to use named arguments Dto with AllFields notation because argument order is not guaranteed.
