Feature request: add new default No Toll Route

A common use case is to choose only routes without a toll. This can be achieved with the following custom setting:

{
  "priority": [
    {
      "if": "toll == ALL",
      "multiply_by": "0.0"
    }
  ]
}

I suggest this should be added as one of the proposed options.

Side question: when using a custom config, is there no way to draw multiple possible routes?

You mean in GraphHopper Maps? Sure, feel free to create a pull request.

Alternative routes are possible with a custom model too but it might take too long to calculate and at a certain point (if start and destination are too far away from each other) alternatives are disabled.
