Bug description:
  [Impact]
  The OpenStack Octavia service will not work after upgrade to Hirsute.

  [Test Plan]
  Execute the gate tests for the octavia charm, which performs a full cloud deployment and confirms successful creation and operation of load balancer.

  [Regression Potential]
  The patch has already been available in the upstream branch-20.12 and has been released in our Focal packages as part of the 20.03.2 point release update for some time.

  [Original Bug Description]
  When using Openstack Ussuri with OVN 20.03 and adding a floating IP address to a unbound port the ovn-controller on the hypervisor repeatedly reports:

  2021-03-02T10:33:35.517Z|35359|ovsdb_idl|WARN|transaction error: {"details":"RBAC rules for client \"juju-eab186-zaza-d26c8c079cc7-11.project.serverstack\" role \"ovn-controller\" prohibit modification of table \"Port_Binding\".","error":"permission error"}
  2021-03-02T10:33:35.518Z|35360|main|INFO|OVNSB commit failed, force recompute next time.

  The seams to be because the ovn-controller needs to update the
  virtual_parent attribute of the port binding *2 but that is not
  included in the list of permissions allowed by the ovn-controller role
  *1

  *1 https://github.com/ovn-org/ovn/blob/aa8ef5588c119fa8615d78288a7db7e3df2d6fbe/northd/ovn-northd.c#L11331-L11332
  *2 https://pastebin.ubuntu.com/p/4CfcxgDgdm/

  Disabling rbac by changing the role to "" and stopping and starting
  the southbound db listener results in the port being immediately
  updated and the floating IP can be accessed.
