bundle with bionic-queens

One instance succeeded with the bundle, then
$ juju config neutron-openvswitch firewall-driver=openvswitch
has been set.

After Juju settles down, the next instance was launched, but failed with the error.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

nova-lxd is EOL and no longer in development.
