vcloud-director (for port-forwarding): should re-authenticate when token expires

[aledsage]

I ran a test in my debugger; it stopped at a breakpoint over night. In the morning when it resumed, I got the error below.

I'm guessing that the authentication token had expired, and that we have no logic for vcloud-director to get a new token.
