Add documentation for podman compatibility

[Thomas-Waldbillig]

Hi,

I recently switched to podman and i am having issues configuring this plugin. I tried following a couple of tutorials that said it can work togetherm but so far I could not get it to run correctly on my linux machine

If you could add something in your document or configuration interface, it would be much appreciated

keep up the good work Thomas

Right now Podman is not supported, we're tracking that in #3241
