During a minor update of a HA controller node, an initial step
consists in moving away any virtual IP hosted on the node to be
updated. But when the HA control plane only has 1-node, this step logs
an error, because there is no other available node to move the virtual
IP to:

Change abandoned by Emilien Macchi (<email address hidden>) on branch: master
Review: https:/
Reason: The gate is currently hitting the "docker api 429" issue, see #tripleo channel for more details. I'll abandon that patch so it's cleared from the gate. Please do not restore it as I'll take care of it when the gate is stable again. Thanks for your understanding and patience!
