Change package installs for Stein and OS upgrade

After upgrading to a new OS we might not have all the necessary
packages, so install them. The list was taken from deployed-server
preparation script. Also change the UpgradeInitCommonCommand for
Stein. e.g. we no longer require Ansible and Ansible-Pacemaker on the
overcloud, as Ansible is now being executed from undercloud only.
