ci: use dump_packages.py callback to get packages used by role

[richm]

This adds the dump_packages.py callback which will dump the arguments to the package module (except for state: absent) to the integration test run logs. The output looks like this: lsrpackages: pkg-a pkg-b ... We will have tooling which will scrape the logs to extract the packages used at runtime and testing for all of the supported combinations of distribution and version.

This also ensures the weekly-ci PR git commit message conforms to commitlint.
