upgrade:
- The entire repo build process is now idempotent. From now on when
the repo build is re-run, it will only fetch updated git
repositories and rebuild the wheels/venvs if the requirements
have changed, or a new release is being deployed.
- The git clone part of the repo build process now only happens when
the requirements change. A git reclone can be forced by using the
boolean variable ``repo_build_git_reclone``.
- The python wheel build process now only happens when requirements
change. A wheel rebuild may be forced by using the boolean variable
``repo_build_wheel_rebuild``.
- The python venv build process now only happens when requirements
change. A venv rebuild may be forced by using the boolean variable
``repo_build_venv_rebuild``.
- The repo build process now only has the following tags, providing
a clear path for each deliverable. The tag ``repo-build-install``
completes the installation of required packages. The tag
``repo-build-wheels`` completes the wheel build process. The tag
``repo-build-venvs`` completes the venv build process. Finally, the
tag ``repo-build-index`` completes the manifest preparation and
indexing of the os-releases and links folders.
