Do not run fwaas API tests in smoke

Now that we are running full tempest against neutron, and because fwaas

test from smoke as part of the effort to only test advanced services
against neutron and not against all projects.

The fix checks whether volume exist before operating with it.

disable neutron network tests that fail too much

The neutron team has deferred addressing these issues until K1. They
are basically preventing any Icehouse code from landing on any project
due to the incredibly high failure rate.

Disable these tests until the neutron team can address the underlying
issue.
