Description

More or less a subset of #263.

This PR updates bus notification code to use route and trip data from OTP2 data structures, and improves logging when sending bus notifications.

👍 Looks good to me.

There are a number of systems with regional agency indicators in the GTFS IDs, I think we're facing that with the MTC pretty soon.

Approving, but need to clarify: This PR does not include the additional logging in CheckMonitoredTrip should it?

@br648 This PR covers the logging for the bus notification stuff, not the additional logging for itinerary checks.
