Script to install modules during integration

This script closely follows the script in
openstack/puppet-openstack-integration to provide installation of
modules in both testing contexts: zuul and local development.

+# This script installs the puppet modules required by infra to run acceptance
+# tests. It can run in two different contexts. In the first case, it is running
+# as part of a zuul driven check/gate queue where it needs to opportunisticly
+# install patches to repositories that are not landed yet. In the second case,
+# it is running from a base virtual machine by the beaker tooling where it needs
+# to install master of all openstack-infra repos and the tagged versions of all
+# library modules.
+
+# This script uses system-config/modules.env as the source of truth for modules
+# to install. It detects the presence of zuul-cloner to decide if we are running
+# in a zuul environment or not.
