Implicit converter from Java Duration to Timeout

[johanandren]

There is an implicit conversion from FiniteDuration to Timeout which allows this:

val myTimeout: Timeout = 4.seconds

Would be nice if there was the same for java.util.Duration so that this would work:

val myTimeout: Timeout = config.getDuration("my-app.timeout")

for the Timeout from config case one can use the Java API (from Scala):

implicit val timeout: Timeout =
    Timeout.create(system.settings.config.getDuration("weather.routes.ask-timeout"))

This duration/timeout issue has been a nit of mine for years. I can take a look when we're ready.

typed/untyped system:

import scala.concurrent.duration._
implicit val timeout: Timeout = system.settings.config.getDuration("key").toMillis.millis
