Subject: [PATCH 01/41] [CI] Refactor common functionality into separate script

This patch refactors some common functionality present in the CI scripts
to a separate shell script. This is mainly intended to make it easier to
reuse this functionality inside of a Github Actions pipeline as we make
the switch.
