Highway, ferry and tracks tags missing in the response to route

[monteirodom]

When requesting a route, one can ask to (try to) avoid ferry, highways, tolls.
It's a good behavior to have some information in the response, allowing to know if such segments have actually been used or not.
A tag toll=true is actually added to a segment on the response as documented
But contrary to the docs, ferry=true should also be added to a ferry segment in the response, but it is actually missing.

Just noticing, this was solved in #3816.
