As Guillaume pointed, many selftests create namespaces with very common
names (like "client" or "server") or even (partially) run directly in init_net.
This makes these tests prone to failure if another namespace with the same
name already exists. It also makes it impossible to run several instances
of these tests in parallel.
This patch set conver all the net selftests to run in unique namespace,
so we can update the selftest freamwork to run all tests in it's own namespace
in parallel. After update, we only need to wait for the test which need
longest time.
