Merge pull request #273562 (add aws-gate package)

This adds aws-gate, an AWS SSM Session manager client and while I'm not
using the program myself, I reviewed the work and did some rudimentary
testing (eg. whether the session-manager-plugin works).

Additionally, it also adds the unix_ar Python package which was used for
the GNU/Linux bootstrap of the aws-gate package but has been patched out
during the review. We decided to keep the unix-ar package nonetheless
since the package seems to be rather low-maintenance and the package
author is willing to keep maintaining the package.

I'm merging this right now because the package is low-impact, meet the
packaging requirements and all builds pass (including the ones for
unix_ar).
