Per [1] Docker uses API version 1.26 since daemon version 1.13.1. Kolla Ansible forced a limit on the Docker API version reported to Zun of 1.24 which was surprising users and preventing usage of Docker runtime selection via Zun. The default of Zun is 1.26 [2] which enables runtime selection. Zun does not use this parameter for anything else atm.
