Public bug reported:

Currently the OVN driver initialization does not work with uWSGI because
the initialization is different than eventlet and the
post_fork_initialization() method [0] does not get called in the
process.

The post_fork_initialization() method is the one responsible for a few
things:

* Starting the OVN database connections
* Starting the maintenance task
* Overwriting the agent and availability zone methods for OVN use [1]
* Running the database synchronization script (in log or repair mode) [2]

These steps would need to be factored out to adhere to the uWSGI
initialization process.

How to reproduce:

Deploy Devstack with OVN
(https://docs.openstack.org/neutron/latest/contributor/testing/ovn_devstack.html)
with NEUTRON_DEPLOY_MOD_WSGI=True set in local.conf.
