Comment 1 for bug 1753471

Also hit this issue with containerized setup. Investigated a bit and found 3 places where fix is possible

1. In Neutron, at conf load stage. https://github.com/openstack/neutron/blob/master/neutron/conf/plugins/ml2/drivers/ovn/ovn_conf.py#L231
Solution will be klunky: parse config string with possibly several hosts defined, resolve all addresses and re-assemble string back

2. In ovsdbapp https://github.com/openstack/ovsdbapp/blob/master/ovsdbapp/backend/ovs_idl/idlutils.py#L183
Slightly better, here we have single record to process

3. In ovs somewhere here: https://github.com/openvswitch/ovs/blame/master/python/ovs/socket_util.py#L237

Best solution probably to fix in ovs, but fix in ovsdbapp is smaller and easier to test
