Title:
  octavia loadbalancer refuses to manually failover

Status in octavia package in Ubuntu:
  New

Bug description:
  On 2020-04-09, we discovered that the failover command creates a new
  LB instance, kills the old instance (which does not exist), and then
  fails to plug a network port as there is already an ovs port on the
  host for some reason.

  This was discovered during a failed migration attempt using an amphora
  image, so an attempt was made to use the failover command. We run the
  Octavia loadbalancer with only a single amphora (standalone).

  Some of the octavia units were missing the configuration for rabbitmq,
  most likely since October 2019, which was fixed when we discovered it.

  SEG escalation found the following:
  - The duplicate db entry of port bindings causes a `loadbalancer failover` to fail similarly to what is reported here
  - Removing the additional ml2_port_bindings entry does not fix the issue
