juju refresh ovn-chassis --channel 22.03/stable

Once ``ovn-chassis`` units settle in the ``active/idle`` state after the config
change, restart OVN Metadata agents with:
.. code-block:: console
juju run -a ovn-chassis 'systemctl restart neutron-ovn-metadata-agent'
.. note::
Restart of Neutron OVN metadata agents is especially important when
upgrading from OVN versions lower than 20.09. These versions used table
``Chassis`` in SB database for chassis registration whereas newer versions
use ``Chassis_Private``. Without the service restart, metadata agents will
not re-register in the new database table and Neutron will not be able to
detect these agents.
