Public bug reported:
https://github.com/openstack/neutron/blob/2702baed390d094b0eac07d0ae167ed236868d00/neutron/plugins/openvswitch/agent/ovs_neutron_agent.py#L1327
The ovs agent will currently accepts anything for local_ip, and sends it
to the plugin with the sync_tunnels rpc, and then all other agents will
try to make tunnel ports using it as the remote_ip. Then the only way to
get rid of it is to manually delete the row in the DB.
If tunneling is enabled, netaddr.IPAddress() could be used to validate
that local_ip is a proper IP address. Only IPv4 tunnels are currently
supported for GRE - not sure about VxLAN. Maybe a check that local_ip
actually exists on the host too.
