4 Refactor PyPI release-verify and release-merge templates to download
5 distribution files from a PyPI staging index and upload the files to a
6 PyPI release index. Remove all the builders that were previously used.
7 Call pip upgrade to install latest version of setuptools and twine.
8 Split the PyPI job groups because the verify & merge templates do not
9 accept the same arguments as release-verify & release-merge templates.
10 Remove stream, branch usage; just one PyPI release job per project now.
11 Extend the PyPI release yaml file schema for log_dir and other values.
12 All this makes the PyPI release ver/mrg templates highly similar to the
13 release-job ver/mrg templates. Revise documentation appropriately.
14 Move the PyPI release features to the lf-release-jobs.(rst,yaml) files.
15 Extend the release-job.sh script to have pypi release functions, and
16 drop the pypi-tag-release.sh script.
