Update podman image Dockerfile to support Podman in container
[NO TEST NEEDED] Can not test this in CI/CD system since it needs to be
merged in order for the Dockerfiles to even work.
Modified the /etc/subuid and /etc/subgid to be able to run in rootless
containers. The Range can not be the same as on the host.
Add /home/podman/.config/containers/containers.conf to automatically
mount /proc on /proc while inside of the container. This prevents
additional permissions being required that are blocked when not in
--privileged mode.
Setup volumes for /var/lib/containers and
/home/podman/.local/share/containwers
This will prevent the errors where people are doing overlay on overlay.
