Differences in default request headers between Kitura-NIO and Kitura-net

[pushkarnk]

I tried printing the default HTTP request headers using this simple app:

import Kitura
import KituraNet
import Dispatch

// configure the router
let router = Router()
router.get("/test") { request, response, _ in
    for header in request.headers {
        print(header)
    }
    try response.status(.OK).end()
}

// start Kitura
DispatchQueue(label: "server").async {
    Kitura.addHTTPServer(onPort: 8080, with: router)
    Kitura.run()
}

//let the server come up
sleep(2)

//make a request
_ = HTTP.get("http://user:pass@localhost:8080/test") { response in
    print("Response = ", response?.statusCode ?? "no response")
}

With Kitura-net I see:

("Host", Optional("localhost:8080"))
("Accept", Optional("*/*"))
("Authorization", Optional("Basic dXNlcjpwYXNz"))

and with Kitura-NIO I see:

("Authorization", Optional("Basic dXNlcjpwYXNz"))
("User-Agent", Optional("Kitura"))
("Host", Optional("localhost"))

This needs investigation.
