Looks like this was fixed last year in a few different changes, all of
which are linked here:

https://bugs.launchpad.net/neutron/+bug/1968606

Running this tool again manually on master branch I didn't see the
failures so I'll close this, please re-open if it happens again.

Title:
  neutron-ovn-db-sync-util: Unhandled error:
  oslo_config.cfg.NoSuchOptError: no such option keystone_authtoken in
  group [DEFAULT]

Status in neutron:
  Fix Released

Bug description:
  If you have a neutron.conf containing a nova section that makes use of
  the `auth_section` configuration option to point the keystone loader
  at credentials in a different section instead of repeating it the tool
  will crash.

  The neutron-server is just fine with loading the same configuration. I
  suspect there is some initialization missing in the tool to allow it
  to parse this correctly.

  The fix provided for bug 1882020 did address this at the time, but
  since then it has returned.

  Looking at the traceback I suspect the adding of segments support made it appear again:
