Adding the mgmt zone broke zonemake - it uses Python's ConfigParser, which 
doesn't like having more than one config section by the same name. Also, 
the nonexistent cabal decided that switches in the mgmt zone was dumb.

The zonefile has been hacked up a bit, and now DRAC/LOM/whatever for 
machines is under $machinename.mgmt.ucc... and switches are 
$switchname.ucc... That is, if the machine already has a hostname, its 
management interface will be in the .mgmt. zone. If not, it's not.
