Add Engine version to docker node ls 

This adds the Engine version to `docker node ls`, and `.EngineVersion` as a
template option.

With this patch applied:

    docker node ls
    ID                            HOSTNAME                STATUS              AVAILABILITY        MANAGER STATUS      ENGINE VERSION
    wp9231itoqsh4rqceojqo01vp *   linuxkit-025000000001   Ready               Active              Leader              18.01.0-ce
