Do we want to support podman in grpc4bmi?

[Peter9192]

Podman is an alternative to docker. It's used as alias docker=podman.

However, this is incompatible with grpc4bmi. In grpc4bmi, we used the docker python library like so:

import docker
client = docker.from_env()

This fails with

...
ConnectionError: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))

During handling of the above exception, another exception occurred:

I haven't looked much into it, but if there's no clear way around it, than perhaps podman-py could be an option
