Handle routing engine http statuses

[FFKL]

Hello! I migrated vroom from v1.13.0 to v1.14.0 and got a Missing durations error. Then I discovered that the problem is connected to the requirement of adding the postfix ors/v2 to the host setting. But the main problem is that vroom doesn't handle any HTTP status codes, so it's hard to debug such errors. Perhaps a good option would be to throw a RoutingException?

The status just drops https://github.com/VROOM-Project/vroom/blob/1fd711bc8c20326dd8e9538e2c7e4cb1ebd67bdb/src/routing/http_wrapper.cpp#L123-L126

and I received an error related to the request body https://github.com/VROOM-Project/vroom/blob/1fd711bc8c20326dd8e9538e2c7e4cb1ebd67bdb/src/routing/http_wrapper.cpp#L161-L164
