Allow using nested object values when piplining

[cadecairos]

I've got a case where a response looks like this:

{
  obj: {
    id: 1
  }
}

And I'd like to do this in a future batch request: "/foo/$0.obj.id/bar", but it seems I can only refer to one level of an object.

This can be better accomplished with Hoek.reach

If the issue was already released, you need to open a new one. Otherwise we lose the history of what was included in each release.
