- Define actions that have an equivalent section in existing Release

- Assume the commits that have the necessary changelog makrup are merge
  commits from GitLab and transform them into messages and proper links
- Put the resulting changelog into the proper place in
  doc/arm/changelog.rst

  these should be generated from the `git log`, with release notes being
  subject to more scrutiny and further editing
