Bug Description
During the container upgrades, the neutron containers in particular, are loosing all namespaces.
This causes the DHCP and floating IP connectivity issues, ultimately DHCP leases will be not be served during this time, so that instances will loose network connectivity.
This issue is happening very early inside the run_upgrade script roughly at lxc-hosts-setup.yml and I expect this issue present until the setup-openstack.yml (neutron portion) has been finished.
