Hello Neutrinos:

I would like to highlight something I found during the implementation of [1]. The periodic workers are currently not executed when the WSGI module is configured when using the ML2/OVS mechanism driver (ML2/OVS is still under development). In order to fix that, I've pushed the following patches:
* Set the Neutron server workers name: https://review.opendev.org/c/openstack/neutron/+/922090/
* Add a new process to spawn the plugin services in the Neutron server: https://review.opendev.org/c/openstack/neutron/+/922110
* (devstack) [Neutron] Add a new Neutron service: neutron-services-server: https://review.opendev.org/c/openstack/devstack/+/922125

Now we have periodic and experimental jobs using WSGI, I've pushed https://review.opendev.org/c/openstack/neutron/+/922182 to test both the Neutron and the devstack patches.

Regards.
