Changes to WaitForADDomain

- BREAKING CHANGE: Refactored the resource to handle timeout better and
  more correctly wait for a specific amount, and at the same time make
  the resource more intuitive to use. This change has replaced parameters
  in the resource (issue dsccommunity#343).
- Now the resource can use built-in `PsDscRunAsCredential` instead of
  specifying the `Credential` parameter (issue dsccommunity#367).
- New parameter `SiteName` can be used to wait for a domain controller
  in a specific site in the domain.
