Podman containers monitoring support #1985
Description
Is your feature request related to a problem? Please describe.
When using podman instead of docker, glances fails with an exception.
Describe the solution you'd like
Glances should not fail to start. Podman containers should be visible in a similar manner as docker containers. Podman supports Docker API v1.40: https://docs.podman.io/en/latest/markdown/podman-system-service.1.html
Describe alternatives you've considered

Steps to reproduce
- Install podman
- Enable podman service `systemctl start --user podman.service
- Set
DOCKER_HOSTenvironment variable:
export XDG_RUNTIME_DIR=/run/user/$(id -u) # this should not be needed - XDG_RUNTIME_DIR should be already set on your system
export DOCKER_HOST="unix://$XDG_RUNTIME_DIR/podman/podman.sock"- Start glances - it hangs with the following error (needs to be ctrl-c'd):
glances
