    Undercloud upgrade docs -- "yum update" necessary packages

    Expand the list of packages to `yum update` prior running `undercloud
    upgrade`:

    * openstack-tripleo-common -- we use direct Python imports from common
      to tripleoclient.

    * openstack-tripleo-heat-templates -- nowadays we upgrade the
      undercloud based on t-h-t content, we need the latest content before
      we trigger the upgrade.
