Since we have SRV DNS entries for our afsdb services, we don't need to
explicitly list their IP addresses here. From the man page:
For the client CellServDB, it may be desirable to make the client
aware of a cell (so that it's listed by default in /afs when the
-dynroot flag to afsd is in use, for instance) without specifying
the database server machines for that cell. This can be done by
including only the cell line (starting with ">") and omitting any
following database server machine lines. afsd must be configured
with the -afsdb option to use DNS SRV or AFSDB record lookups to
locate database server machines. If the cell has such records and
the client is configured to use them, this configuration won't
require updates to the client CellServDB file when the IP addresses
of the database server machines change.
Thus we just keep the openstack.org entry. We're have not been
keeping the list in here up-to-date with the grand.central.org version
(well, not since 2014 anyway). Since we don't really need to track
any of these, just remove them.
