Docker 1.10 Upgrade
Adds a separate playbook for Docker 1.10 upgrade that can be run standalone on a pre-existing 3.2 cluster. The upgrade will take each node out of rotation, and remove *all* containers and images on it, as this is reportedly faster and more storage efficient than performing the in place 1.10 upgrade. This process is integrated into the 3.1 to 3.2 upgrade process. Normal config playbooks now become 3.2 only, and require Docker 1.10. Users of older environments will have to use an appropriate openshift-ansible version. Config playbooks no longer are in the business of upgrading or downgrading docker.
