kolla/tools/kolla-ansible doesn't exist but is mentioned several times in docs

kolla/tools/kolla-ansible doesn't exist, but is still mentioned in several places in the docs. I'm currently unable to deploy kolla-kubernetes on a 3 node kubernetes cluster installed with vagrant and kargo. Are there any validated docs that work with latest version?
