(QE-62) log into vagrant boxes as root/administrator

Another brittle fix.  Once vagrant boxes are up we ssh in, copy the vagrant key into root's homedir and then log out.  We then log back in as root using the vagrant key.  That way we can then operate as root, as we do with our other provisioned boxes.

This has not been tested on windows as I haven't found a working windows vm to test it on.  Otherwise works.
