HTTP REST listener needs better support for mapping route/target not in params.

localhost/api/users/photo?id=1

1. /api/ is the basepath.
2. /users/ is the target
3. /photo is the route.
4. id is the param, which is mapped to the request body.

Need to consider cases where we have nested routes/targets. localhost/api/accounts/sweden/view?query=*

• do we prefer nested targets or nested routes? probably nested routes.

Fixed.
