This patch adds a new TripleO specific playbook which will call the
check_latest_packages_version role hosted in validations-common. This
playbook will test if the python3-tripleoclient package is at its latest
version on the Undercloud before starting an upgrade.
Note1: The check-latest-packages-versions validation hosted in
validations-common will be refactored to only test non TripleO packages.
Note2: The documentation automation has been modified to point to the
external role official documentation.
