Add vnodes to the nodes table for nodes we're adding. 

Handle interfaces we didn't find on the switch.

Use newnode_reboot to reboot nodes, since they won't yet be at their
'permanent' IP addresses.

Changed my mind again on what state the new nodes should be put into
once they've been created. Now, they go into emulab-ops/hwdown, and
boot into the FreeBSD MFS. This way, the admins have a chance to look
at them before they loose them on the world, and they're booted into
something that runs SSH, so we don't lose control over nodes that
don't have power controllers (which newnode doesn't currently handle,
anyway.)
