Support for typesafe java.time.Duration

[costimuraru]

Sample of reference.conf file: foo = 300ms

We should be able to map this to a Duration attribute.

Exception thrown:

You want to give it a try and submit a PR?

@howardyuan, yup. I'm going to do it in the 2.x branch if that's ok with you guys.
