docker service is not used and takes ~150MB of RAM on all nodes

Fixes okd-project/okd#243

I’m all for disabling docker, but this looks like a real hacky way of doing it, so I think this should be noted in the commit message. (Properly disabling services is blocked by an ignition/systemd issue: coreos/fedora-coreos-tracker#392

OVN failed to rollout on one node

Let's put this on docker.socket instead - if you do it on the .service, the socket will still exist, it will just fail to work, which might confuse clients.

(Also FWIW I don't see any harm to having this on the master branch too, but we can deal with that when we get to merging the fcos branch)

This adds a condition to docker.socket which it can't fullfil,
so that OKD nodes would not run unused docker service.
