Hello

Documentation improvement needed as shown below.

On Step 8 of the procedure doc "Migrate to OVN":

#### Currently ####

8. Deploy the Neutron OVN plugin application

juju deploy neutron-api-plugin-ovn \
   --series focal \
   --config dns-servers=="1.1.1.1 8.8.8.8"

####

#### Should be updated to ####

8. Deploy the Neutron OVN plugin application

juju deploy neutron-api-plugin-ovn \
   --series focal \
   --config dns-servers="1.1.1.1 8.8.8.8"

####

The double equals-to i.e == should actually be =.

Impact:

This double equal to made the value assigned to the config along with one equal to i.e

$ juju config neutron-api-plugin-ovn dns-servers
=1.1.1.1 8.8.8.8
$

and caused complete DHCP outage in the openstack overlay networking.

Thanks & regards

    Fix typo in OVN migration guide

    The OVN migration guide accidentally had a '==' in the
    example for setting dns_servers, which resulted in an
    invalid IP such as '=10.0.0.1'. Fixing allows DHCP to
    succeed.
