  - Allow overriding docker version in prepare-docker-dind
    
    This change allows overriding of docker version to be installed
    when calling prepare-docker-dind role.
    It also enables downgrading, allowing the
    given version to be taken into account. Previously
    the specified version was completely ignored.

  - Specify source ip for rancher agent
    
    This change explicitly sets cluster_ip as rancher agent source ip.
    This avoids eventual problems with ip autodetection, especially that
    we know the correct ip.
