Feature request: Podman support

[neonfuz]

Support podman as an alternative to docker. I have not done a deep investigation on what this will entail but as we figure out details they can be tracked here.

we don't do anything super exotic with docker so i think this should be doable and i'm generally favorable to the idea; my main qualm is knowing that podman is very much under active development and may lack the stability of docker. assuming there are no show-stoppers i am in favor of some kind of abstraction layer that can alternate between docker and podman like you mentioned.

Generally speaking, dockerfiles just work on podman. There's just a few features that aren't supported, or work a little differently. Usually it's something like there's a new way and an old way of doing a thing in docker, and podman only supports the new way, so you just upgrade your docker code and it works with both.

Podman even has a docker-compat package which gives you a docker command which functions exactly the same as docker.

Just needs testing and probably a few fixes
