It seems we're using the default docker0(docker)/cni0(podman) bridges
for these containers. It would be good to remove dependencies on these
default bridges.
Some other containers changed that have the same issue:
- ironic_inspector_init_dnsmasq_dhcp_hostsdir
- nova_statedir_owner
- swift_setup_srv
- swift_copy_rings
- horizon_fix_perms
