Solution:

$ apt-get install python3-docker

We should document it in koll-ansible dependency section.

I do not think this is all we need. AFAICS python3-docker is needed on all nodes, not just the node kolla runs on. At least i find the doc changes miss-leading (not even sure it is needed for the kolla-node, but it is needed for controller/computes for sure).
