Use CRI-O with kubeadm.
Before switch to kubeadm we used to use manual approach for installing all the bits with option for switching container runtimes between docker and cri-o. With this patch we re-gain that ability with simply setting appropriate container engine variable for devstack-plugin-contaier to use either CRI-O or default Docker. Depends-On: https://review.opendev.org/c/openstack/devstack-plugin-container/+/817231 Change-Id: I273888a7428611b40802dc5dd53fcee864ce43da
