[Feature] Add -extended-stats for *nix platforms

On *nix platforms, there is now a `-extended-stats` option that will
print out some extended statistics for the test. The statistics are
based on information gleaned from the `TCP_INFO` of the underlying TCP
connections. What is implemented so far is just a proof of concept of
the extended stats that could be calculated. Depending on what users
want, we can add additional extended statistics.
