Title:
  Neutron attempts to schedule DHCP agents even when intentionally not
  in use

Status in networking-ovn:
  Fix Released
Status in neutron:
  Fix Released

Bug description:
  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.
