Request Headers for Transit Feeds bulid-config.json

[ctriley]

Is your feature request related to a problem? Please describe. I want to be able to use the build-config.json file to fetch static GTFS files that require API keys.

Describe the solution you'd like Similar to router-config.json I'd like a "headers" key in the build config. Example from routers-config.json

  "updaters" : [ {
    "type" : "real-time-alerts",
    "frequencySec" : 30,
    "url" : "http://developer.trimet.org/ws/V1/FeedSpecAlerts/appID/0123456789ABCDEF",
    "feedId" : "TriMet"
  }, {
    "type" : "vehicle-rental",
    "network" : "socialbicycles_coast",
    "sourceType" : "gbfs",
    "language" : "en",
    "frequencySec" : 60,
    "allowKeepingRentedBicycleAtDestination" : true,
    "url" : "http://coast.socialbicycles.com/opendata/gbfs.json",
    "headers" : {
      "Auth" : "<any-token>",
      "<key>" : "<value>"
    }

proposed build-config.json

{
  "transitFeeds": [
    {
      "type": "gtfs",
      "feedId": "wmata-dc-us",
      "source": "https://api.wmata.com/gtfs/rail-bus-gtfs-static.zip",
      "headers": {
          "api_key": ""
      }
    }
  ]
}

Describe alternatives you've considered I can fetch the gtfs files and store them in a folder outside of OTP startup, but this is less clean and requires additional scripting.

You will need to change the HttpDataSource in otp to do this. Should be stright forward. If you want some guidence, I recommends calling into one of the developer meetings.
