Merge nereid-test into nereid

With 3.4 nereid-test module - an optional tryton
module which helps in testing nereid features,
has been merged into core nereid. Just like before
this will not be listed in tryton module list.
Deprecate Database based URL routing

Was due for deprecation in 3.4. Goodbye database routing and
only have route decorator based routing.
Update must be a list of module to update
