This patch provides a convenience script to check for the current
version of any package on PyPI, then output it in various ways.
This script is used in the SHA updating script in order to provide
a current set of critical packages to ensure that each SHA bump
includes an update to a current version of pip, setuptools and
wheel but also to ensure that they are pinned to a specific version
with this particular set of packages.
This ensures that we keep current with these packages as they
change, but also ensures that the versions tested for each tag are
the versions used forever.
The patch also ensures that any package installed by pip is upgraded
to the expected versions.
