The previous version just created a network name space which does not allow us to also test additional namespaces, e.g. for unix domain sockets. This commit uses runc to create a fully namespaced container to run a test in. It creates a container, configures the network interfaces in the new network namespace before starting the container. A OCI config.json template is used and then customised for a given test based on command line arguments. Finally, instead of iperf, we use the socket stress test from https://github.com/linuxkit/virtsock as it provides finer-grained control over the traffic patterns (e.g. long lived vs lots of short lived connections).
