nova-manage floating ip fixes

* Add pool, interface to 'floating list' output
  These columns were added to the floating_ips table in
  https://review.openstack.org/2892 and are not visible elsewhere
* Fix 'floating delete' to skip network/broadcast addresses
  Makes the delete command match the create command behaviour
  introduced in https://review.openstack.org/2663
* Address changes listed in bug 817281
  Change host column in output to project ID, change hostname
  column to uuid
