Need a way to get the TripOnServiceDate and the pick up / drop off for it in GTFS GraphQL API from a leg

[miklcct]

I am trying to implement a feature on a client side to handle disruptions where a train skips the alighting stop, and to get this I need to find where the train will stop next and let passengers out.

There is currently no direct way to get the TripOnServiceDate from a leg. I need it to check if there are any intermediate stops which are cancelled.

In addition, the StopCall type referenced from TripOnServiceDate, and also LegTime doesn't have the pick up / drop off type listed which I need as well.

@vesameskanen please help to make the existing GTFS GraphQL API to use TripOnServiceDate when appropriate such that I can resolve #6206 . There has been further discussion that the Stoptime model is bad.

I don't have short-term plans for adding the TripOnServiceDate to other types personally but it was designed to be used elsewhere as well so feel free to add it. I can help you a bit with the design perhaps.
