Subject: Routes: Add `/costs` route

Render the `costs` field of a `Chouette::Route` as JSON. This lives at:
http://stif-boiv.dev:3000/referentials/4/lines/1857/routes/7/costs.json

I want this in order to get the distance & time costs of a route so that
I can merge them with `JourneyPattern#costs` on the frontend on
`JourneyPatternsCollection#show`.

Refs #6203
