Use {URI} parameter in Navitia generic API

The {URI} parameter means that the call parameters are embedded in the query URL and are not, as in most cases, at the end of the query URL.

Example : To retrieve all the " stop_points " on metro line 1 (line:IDFM:C01373 )

We use the method : /v2/navitia/{uri}/stop_points/{id} 

With the call parameter in place of {id}: lines%2Fline:IDFM:C01373
