add rounting services via open source routing machine

[tobi238]

the service can be used with docker (see https://hub.docker.com/r/osrm/osrm-backend/). build routing data from osm data and start server in a batch file:

:: prepare osm downloaded data:
:: run commands in same folder as karlsruhe-regbez-latest.osm.pbf
docker run -t -v C:/docker/osrm/data:/data osrm/osrm-backend osrm-extract -p /opt/car.lua /data/karlsruhe-regbez-latest.osm.pbf
docker run -t -v C:/docker/osrm/data:/data osrm/osrm-backend osrm-partition /data/karlsruhe-regbez-latest.osrm
docker run -t -v C:/docker/osrm/data:/data osrm/osrm-backend osrm-customize /data/karlsruhe-regbez-latest.osrm

:: start server from same folder
docker run -t -i -p 5000:5000 -v C:/docker/osrm/data/:/data osrm/osrm-backend osrm-routed --algorithm mld /data/karlsruhe-regbez-latest.osrm
