When using the Match service, the response contains hint_data. This additional data doubles the size of the response from the match query and is not needed unless you're also using the viaroute service. It would be nice to have a command line option or service request parameter that disables the output of hint_data at least for the Match service.

The v5 API still sends the hint every time:

Did we forget to add a switch for that during the v4 -> v5 transition or what is the idea behind it? @TheMarex

Lets the user specify us dropping hints in response, resolves #1789.

Adds an `?emit_hints=false` option which lets us skip generating and
emitting hints for Waypoints. This can be used to decrease the response
size when the user does not need hints anyway.

We should think about making `false` the default here in v6.
