Public bug reported:

High level description:

A critical error is thrown when running the neutron-sanity-check script

CRITICAL neutron [-] Unhandled error: oslo_config.cfg.NoSuchOptError: no
such option vf_management in group [DEFAULT]

This was initially seen in a containerized environment configured by
openstack-helm.  The error causes the openstack_neutron-ovs-agent-init
container to fail.

It can also be reproduced in devstack

Step-By-Step:

- Grab the latest devstack as of 2020-07-24.
- Run neutron-sanity-check --config-file /etc/neutron/neutron.conf --ovsdb_native --nokeepalived_ipv6_support

Analysis:
