Note that Kubespray (former Kargo) now supports the kubeadm tool
natively [0]. This speeds up a cluster bootstrapping from an average
25-30 min to a 9 or so. I believe this makes Kubespray a viable option
for upstream development of OpenStack overclouds managed by K8s.
Especially, bearing in mind the #deployment-time effort and all the hard
work work done by tripleo and infra teams in order to shorten the CI
jobs time.

By the way, here is a package review [1] for adding a kubespray-ansible
library, just ansible roles and playbooks, to RDO. I'd appreciate some
help with moving this forward, like choosing another place to host the
package, it got stuck a little bit.
