[OpenAFS] Need to Combine AFS Database & File Servers

Thanks to all.
The bottom line is that AFS 3.6 File Server will figure out where
the Volumes are located after I move the DB servers to the File
Server hardware and change the IP addresses.
There is no need to use  `vos changeaddr'.

One important bit of advice is to keep the existing file
on each file server because it contains a UUID that is used in
the VLDB.
