Description of problem:
A customer is looking to move from ML2/OVS in their current deployment to OVN in a new OSP13 deployment. They currently use dnsmasq settings to pass DHCP option 252 (WPAD) to their clients for site-specific proxy configuration. Option 252 is not currently configured as a supported option by ovn-northd.
This RFE is to add support for option 252 to ovn-northd to be used in conjunction with another RFE for Neutron's networking-ovn module.
