Podman release 0.8.1

Our latest podman release turned out to be a lot of internal plumbing. We had more than 50 commits but most were tweaks that most users would not notice. So I don’t have a singular, hot feature to point you at.

That said, if you haven’t tried the python client to for podman, I recommend you do. It allows you to interact with a remote podman instance via SSH.

Other notable benefits of this release are:

* Fixes to rootless containers including network support using slirp4netns written by Akihiro Suda
* Adjustments to how images are pulled and their metadata
* podman build now supports different isolation mechanims, to better run within a confined container.
* Changes to our integration tests to speed them up
* podman load now supports xz compression
* Tidy up man pages
