Bug description:
  == Impact ==

  Upgrades to OpenStack Ussuri will result in service disruption to the
  network datapath for instances and other virtual networking concepts.

  == Test Case ==

  Standalone
  apt install neutron-openvswitch-agent
  (add proposed pocket)
  apt install neutron-openvswitch-agent
  neutron-ovs-cleanup unit will be restarted

  (UCA)
  add-apt-repository cloud-archive:train
  apt install neutron-openvswitch-agent
  add-apt-repository cloud-archive:ussuri
  apt dist-upgrade

  (neutron-ovs-cleanup will be restarted)

  Full cloud (UCA or distro)
  Deploy OpenStack Train (using Juju charms)
  Create networking, boot instances and confirm connectivity to instances
  Upgrade to OpenStack Ussuri (using Juju charms)
  Networking to instances will be lost

  == Regression Potential ==

  Medium - the fix is purely in package and ensures that the
  neutron-*-cleanup scripts are not started on install or restarted
  during an upgrade.

  == Original Bug Report ==
  Release: Focal/Bionic+Ussuri:

  As part of the package upgrade for neutron-openvswitch-agent, the
  neutron-ovs-cleanup systemd unit is restarted.

  This unit should only be run on reboot, and not during package
  upgrades.

  It has the side effect of removing all ports from the local OVS
  bridge, impacting networking to services.
