demo: podman: New port forwarding behaviour for pasta, minor fixes
Reflect the recent changes in the Podman adaptation (no port forwarding by default). It turns out that by running two iperf3 processes, sometimes slirp4netns blocks the second connection until the first test is done, thus doubling the throughput. Use a single process for slirp4netns with slirp4netns port handling. Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
