dhcp_agent_scheduler is listed as Neutron extension when deploying OVN via the default devstack config [1] but all related tests (Tempest or Neutron tempest plugin) fail because it seems unsupported [2].
Not exposing the extension would avoid blacklisting this tests.
It's not reproduced in gates because the neutron extensions are overridden in tempest.conf [3].
