Podman support?

[kianmeng]

While running the test, I have noticed this library only support Docker. Are there any plans to support https://github.com/containers/podman?

$ mix test

My immediate thought is that this should "just work". But i suppose it suffers from the same issue as the other implementations where you have to define the docker_host env var to point to podman socket.
