Let kubespray choose installed docker version

Specifying 'latest' as the docker_version without specifying a
compatible version of containerd can lead to package dependency
errors.  Let kubespray select the versions to ensure consistency.

Also, installing docker from vagrant installer instead of letting
kubespray install it can lead to the same issues.
