Bug description:
  [Impact]
  The upgrade process from Queens to Rocky fails due to a failure to override a policy file:
  https://paste.ubuntu.com/p/tH4qrvP7mS/

  The issue causes an upgrade action to exit prematurely which leaves
  the dashboard in a broken state as the keystone v3 policy json file is
  not rendered.

  KEYSTONEV3_POLICY = ('/usr/share/openstack-dashboard/openstack_dashboard/conf/'
                       'keystonev3_policy.json')

  This is reproducible without charms by simply doing the following:

  lxc launch ubuntu:bionic neutrontest
  Creating neutrontest
  Starting neutrontest

  lxc exec neutrontest bash
  root at neutrontest:~# apt update
  root at neutrontest:~# apt install python-neutron-fwaas-dashboard
  # ... https://paste.ubuntu.com/p/RMKbNH5DbB/

  root at neutrontest:~# add-apt-repository cloud-archive:rocky
  root at neutrontest:~# python3-neutron-fwaas-dashboard

  [Test Case]
  # apt update
  # apt install python-neutron-fwaas-dashboard
  # add-apt-repository cloud-archive:rocky
  # apt dist-upgrade
  # apt install python3-neutron-fwaas-dashboard

  [Regression Potential]
  Regression potential is low. The fix is just adding a breaks/replaces to python3-neutron-fwaas-dashboard to ensure python-neutron-fwaas-dashboard is removed when python3-neutron-fwaas-dashboard is installed.
