When the containers.conf field "NetNS" is set to "Bridge" and the "RootlessNetworking" field is set to "cni", Podman will now handle rootless in the same way it does root - all containers will be joined to a default CNI network, instead of exclusively using slirp4netns. If no CNI default network config is present for the user, one will be auto-generated (this also works for root, but it won't be nearly as common there since the package should already ship a config). I eventually hope to remove the "NetNS=Bridge" bit from containers.conf, but let's get something in for Brent to work with. Signed-off-by: Matthew Heon <mheon@redhat.com>
