    Docs: encourage users to run apt-get dist-upgrade on target hosts

    Ubuntu 14.04 is currently provided in several point releases, most
    currently 14.04.3. It is possible that users may initially deploy
    roles on a previous point release of Ubuntu, and then later upgrade
    system packages. Most notably, br_netfilter is implemented in it's
    own kernel module in kernel versions >= 3.18. This results in ansible
    fact caches being out of date on subsequent runs, and has caused a few
    bugs to be filed along the way.

    This patch is to hopefully ensure that users are using the most recent
    version of packages when beginning with openstack-ansible.
