Use Sysbox runc to run software such as systemd, Docker, Kubernetes, legacy apps in DockerHost

[stevelorenz]

Recently, I have found a project (a container runtime) called Sysbox which can run "VM workloads" inside a Docker container. So the sys container managed by the Sysbox can run e.g. systemd, Kubernetes inside a Docker container. This startup is recently acquired by the Docker company. I would like to check this runc and use it as the runtime to run outside Docker containers in the comnetsemu. This can replace the current very limited and insecure sibling container mechanism used by comnetsemu. With this new runtime, it is possible to use comnetsemu to emulate a network of e.g. multiple Kubernetes clusters without using e.g. nested VM virtualization.
