Podman/Podman-compose support?

Hi there!

I have made prebuilt docker images, you can pull and run them on Windows/Linux/Mac with Docker. As mentioned in ReadMe, you can also build it with

docker compose build

When using docker-compose + docker instead of podman-compose + podman, it now works.

Ok I did some experiment on my Ubuntu VM. I made some updates for easier working with Podman.

There are some issues which will require workarounds:

1. Podman does not support buildkit cache mount feature. Without it go image building time will be painfully long (not C++ kind of painful, but anyway). This is more of a issue from golang: cmd/go: precompile dependencies for docker image cache golang/go#45474, cmd/go: unclear how to cache transitive dependencies in a Docker image golang/go#27719. With podman you can do

   podman-compose build
   

   by removing the --mount arguments:

   MessageHub/Automation/Docker/Dockerfile

   Lines 4 to 5 in e847d26

   	RUN --mount=type=cache,target=/go/pkg/mod/ \
   	--mount=type=cache,target=/root/.cache/go-build \

   
   Looks like Podman has something similar named buildah but I am not sure how can it work in a similar way, e.g., export DOCKER_BUILDKIT=1 (even without that in latest versions of Docker).
2. I believe podman-compose host network feature is broken at the moment. See network_mode: host have no effect and ports does not opened (podman-compose 1.0.3) containers/podman-compose#397, network_mode=host is not working as expected containers/podman-compose#406. It is said fixed in dev branch, tried without luck.
   As workaround you can start the containers manually (in different terminals):

   docker run --rm --name messagehub_element --network host v2net/messagehub-element
   

   docker run --rm --name messagehub --network host v2net/messagehub
