* Move front-proxy-client certs back to kube mount We want the same CA for all k8s certs * Refactor vault to use a third party module The module adds idempotency and reduces some of the repetitive logic in the vault role Requires ansible-modules-hashivault on ansible node and hvac on the vault hosts themselves Add upgrade test scenario Remove bootstrap-os tags from tasks * fix upgrade issues * improve unseal logic * specify ca and fix etcd check * Fix initialization check bump machine size
