multinode-container-upgrade.yaml usable for mixed upgrade

We need Docker service mapping defined and set to OS::Heat::None so that
we can reuse multinode-container-upgrade.yaml service list both for
initial deployment and for the upgrade. The upgrade will not be broken
by this as its env files are being passed later on the command line, and
they'll take priority and effectively enable the Docker service on
upgrade.

Another change we need for mixed upgrade is to add the TripleoPackages
service, which will take care of updating RPMs on the bare metal and
prevent docker installation from failing with outdated
puppet-tripleo ("Could not find class ::tripleo::profile::base::docker").
