Public bug reported:
OVN has its own native support for DHCP, so the Neutron DHCP agent is
not in use. When networks get created, we see warnings in the log about
Neutron still trying to schedule DHCP agents.
We should be able to disable this code path completely when the DHCP
agent is intentionally not in use.
