[podman] Issue when running with podman > 3

[l0r1s]

Problem

We can't run zombienet using podman version 4 because they removed the suffixing of the pod with "_pod".

Hi @l0r1s, we have more action items in this one?

Hi @pepoviola coulnd't make it work by just modifying pod name to include _pod suffix

Oks, I will try to give a a quick look to check if we can resolve.
Thanks!

I came across this one today. Patching the current master as follows did the trick for me, but the solution is neither complete nor backward compatible.

Hi @s0me0ne-unkn0wn, thanks you for your comment, does it works for both podman v2 and v3 ? Because I had some issue making it works for both versions.

[s0me0ne-unkn0wn]

I'm afraid it's not universal and only works for Podman after the pod naming scheme change. So different podman versions should use different naming schemes. Some stupid ideas on how to resolve that:

1. Create separate providers podman2 and podman3
2. Create a dummy pod on startup and check which naming scheme is used on the host system

@wirednkod you are working on this right? podman v4
