Add OSRM and OTP Docker services with setup scripts

Adds osrm-foot, osrm-bicycle, and otp services to Docker Compose under
a 'routing' profile (opt-in). Setup scripts download Greater London OSM
data and pre-process for OSRM foot/bicycle profiles, plus TfL GTFS for
OTP transit. Routing engine env vars added to .env.sample.
