title: Scala FiniteDuration from String
body: <p>Is it possible to parse a <code>String</code> into a <code>FiniteDuration</code> in Scala without writing custom code? </p>
  
  <p>There is a method on <code>Duration</code>, called <code>create</code>, that accepts a <code>String</code>, however that produces a <code>Duration</code> and not sure how to further use it to create a <code>FiniteDuration</code> from it. There are a few factory methods on <code>Duration</code> that produce <code>FiniteDuration</code> instances, but those imply that I have to parse my string to produce their parameters (their signature expect a long and a <code>TimeUnit</code>). </p>
  
  <p>These types I mention are from <code>scala.concurrent.duration</code>.</p>
  
  <p>Thank you.</p>
