podman unshare: add --rootless-cni to join the ns
Add a new --rootless-cni option to podman unshare to also join the rootless-cni network namespace. This is useful if you want to connect to a rootless container via IP address. This is only possible from the rootless-cni namespace and not from the host namespace. This option also helps to debug problems in the rootless-cni namespace.
