Rodolfo Alonso Hernandez 70a2029ca1 [OVN] Set the default OVN metadata worker number to 0
If the configuration variable ``metadata_workers`` is not set,
the default value for ML2/OVN mechanism driver will be zero.
This value defines the number of separate workers that will
be spawned by the OVN metadata agent. By default, the OVN
metadata proxy handler will be executed inside the same OVN
metadata agent process, in a parallel thread. That reduces the
number of OVN SB database connections to one.

The default value for the ``metadata_workers`` configuration option
has changed to 0 for the ML2/OVN driver. Since `[OVN] Allow to execute
"MetadataProxyHandler" in a local thread <https://review.opendev.org/c/openstack/neutron/+/861649>`_,
the OVN metadata proxy handler can be spawned in the same process of
the OVN metadata agent, in a local thread. That reduces the number of
OVN SB database connections to one.
