A Jenkins JNLP slave docker image with podman
(binaries copied from podman image).
Podman provides docker CLI support for unprivileged users.
Although the container must be privileged to be able to run podman containers
all processes within the Jenkins slave run as unprivileged user jenkins
after the container has been initialized.
In order to make the Jenkins docker plugins work with podman a couple
of compatibility hacks are provided with the docker script.
