Podman helper scripts/examples, including containerized Google Chrome

I’ve updated and improved some helper scripts I have been using for almost 6
months for running “personalized” containers on my desktop with rootless podman.
In particular I’ve been running Google Chrome inside a container with
video and pulseaudio sound working. I’ve also been using almost all development
and testing within containers thus keeping my desktop OS installation relatively minimal
and clean.

The scripts and examples are shared over at https://github.com/castedo/cnest

The main scripts are four scripts averaging less than 40 lines.
A bunch of configuration files show the podman create
options which get the mentioned scenarios working.

If anybody has related tools or approaches that I should mention in the
github README page, please do share.
I’ve included the obvious flatpak and toolbox and a few others.
