[2.3] [Serializer] Enabled camelCase format to be used on denormalize method

 Enabled camelCase formater , that way when hydrating from arrays, attributes as attribute_name could be implemented as attributteName parameter, with getAttributeName and setAttributeName, giving different formating option from setAttribute_name  getAttribute_name.
