To support the handoff of artifacts between the primary and respin pipelines, a pre-build-script is needed for each of the container build steps in the CPaaS pipelines. Also, the container image builds should require signed RPMs from Brew when running a permanent build. This is handled in the script as well as the default values set in each build's container.yaml file.

1. Enable the scripts [1]
2. Add the script [2] to each container build. The script will save/restore the PNC artifact retrieval file in dist-git and also ensure that the build requires signed RPMs (tini and exporter) when a permanent (non-scratch) image is built. The script can be the same for each container image build.
