Title:
  ovn: DVR on VLAN networks does not work

Status in neutron:
  Fix Released

Bug description:
  OVN deployment with DVR router, two networks attached:
  - external (type VLAN)
  - internal (type VLAN)

  OVN configured to use external_ids:ovn-chassis-mac-mappings - to allow
  VLAN backed DVR:

  https://github.com/ovn-
  org/ovn/commit/1fed74cfc1a1e3b29cf86eab2e96048813019b57

  Neutron is setting reside-on-redirect-chassis on the router ports - which essentially makes the router centralized on the network nodes - and disabling DVR.
  With neutron/ml2.conf setting of distributing floating ips - it makes them inaccessible - clearing reside-on-redirect-chassis from lrp options makes the functionality working.
