Support for user-defined-function on feeds

Hi Devs,

With the merge of the patch in [1], we no longer support attaching AQL
user-defined-function to feed. AsterixDB now returns an "incompatible
function language" exception for this case.

Meanwhile, we start to support adding SQLPP user-defined-function to feed.
If you encounter any problems with using it, please file an issue and let
me know. Thanks.

Presumably we should document its limitations, e.g., the SQL++ function 
bodies (like the AQL ones before) used on feeds should not involve joins 
or time-varying functions like current date/time, etc.
