Mapzen isoline tracts support

[nobuti]

Mapzen isolines support, by now, a max of 4 contours (tracts). You can check it with this request:

http://matrix.mapzen.com//isochrone?json={"locations": [{"lat": 40.42028, "lon": -3.70568}], "costing": "pedestrian", "polygon": true, "contours": [{"color": "tbd", "time": 5}, {"color": "tbd", "time": 15}, {"color": "tbd", "time": 20}, {"color": "tbd", "time": 25}, {"color": "tbd", "time": 30}]}&api_key={{matrix_api_key}}

the result for that request is:

{
  "error_code": 152,
  "error": "Exceeded max contours:4",
  "status_code": 400,
  "status": "Bad Request"
}

We need to apply this constraint in the UI for the isolines analysis form. Right now, the maximum is 6 no matter which the provider it is (mapzen or heremaps).

Hey, take into account we don't know anything about providers in the frontend...

We do now with the data from the API. We need to define the default when the API is not there.

I strong believe frontend side should not know anything about providers, and we should not check anything about it. But in any case, this ticket should be done after the quotas thing then...

guysm let's put 4 as max for the time being for everything

[jorgesancha]

Is there a way for us to see how many times we are getting that error? It should be fixed anyhow, but I want to get a sense of how big of a problem this is
