Review comment:
Better load registration manager from configuration rather than constructing
directly from ZKRegistrationManager? Change `format(ClientConfiguration ...)`
to `format(ServerConfiguration ..)`, because registration manager is only
available in ServerConfiguration. This format method is only called by
BookieShell.
