Currently our puppet-requiring hosts (all !bridge) do not manage their
puppet installs. This is OK for existing servers, but new servers
come up without puppet installed.
This is playbooks to manage puppet installs on hosts. It is mostly a
port of the relevant parts of ./install_puppet.sh for our various
control-plane platforms.
Basic testing with zuul-integration jobs is added. Using this in the
control-plane base.yaml playbooks will be a follow-on.
