Recently merged patches[1] seems to have triggered this, other neutron
ovn scenario job likely not impacted as those explicitly enable
extensions.

  Recently merged patches[1] seems to have triggered this, other neutron
  ovn scenario job likely not impacted as those explicitly enable
  extensions.
