    Custom containerized undercloud deployments

    * Parametrize network settings for undercloud deploy to align with
      the undercloud install's undercloud.conf and nova-join's DNS
      config steps.
    * Move the undercloud nameservers defaults to the extras-common.
    * Support extra deploy args for 'openstack undercloud deploy'.
      Defaults to the heat-native mode, may be altered to containerized
      heat-all agents, and other args like keep-running, if wanted.
    * Support custom t-h-t templates for underclouds as well (shares
      the custom t-h-t script and vars with the overcloud-prep-config)
    * Template prerequisite packages installed by the
      undercloud-install.sh script. These should be moved to the
      tripleoclient's 'openstack undercloud deploy', eventually.
    * Allow requested dev env packages to be updated by the
      undercloud-install.sh script (defaults to update nothing,
      which is backwards compatible). Note, this has nothing to the
      prerequisite packages.
    * Document missing variables for the undercloud-deploy role.
    * Document hacking dev branches for customized underclouds.
