Code Issues Proposed changes

Make `OVNMechanismDriver.post_fork_initialize` callback cancellable

Browse Source 
If the callback method ``OVNMechanismDriver.post_fork_initialize``
fails, the callback manager must raise an exception and finish the
process. If that happens in a Neutron worker, the
``oslo_service.service.Services`` class will restart the process.

The neutron-lib version is bumped to 3.9.0. It contains [1], needed
for this patch.
