Designate: Clean up deprecated Rabbit* parameters

The Rabbit* parameters in designate templates were deprecated when
the Rabbit* parameters were deprecated[1] in all template files, but
these parameters were not removed by the clean up commit later.

This change removes these leftovers because these parameters have
been ineffective for a while.
