Utilize more scripts to handle candlepin branching

This reuses the existing branch_project and branch_push scripts to
handle candlepin-packaging's branching. branch_project is modified to
update package_manifest.yaml as well as some setting files.

For CI it uses the branch-candlepin script inside the repository while
also using the release_pipeline script to kick off Jenkins.
