No idea how this happened, but reviews started failing the
pep8 gate job. The failures are legitimate, see the commit.
I guess the pep8 tests became smarter and found these issues.

using --stateful and --no-stateful flag on security group.
This allows a user to create security groups with stateful
false.

Added "qos_network_policy_id" to "port show" command. Because this is
just a read-only parameter and is read from the SDK port definition,
this patch only modifies the corresponding tests.

This patch is adding this new parameter to the test bench.

We had this library capped at a release that is a few years old. Now
that we have dropped py2 testing, we can pick up the latest version.

This uncovered a few things to clean up. Mostly the fact that mock is
now a part of the StdLib unittest since Python 3.3.
