Fix lower_constraints - six verison should be bigger

Builds fail due to autobahn using newer six package.
We should use version 1.11.0 instead of 1.10.0.

GateFix: Fix the scenario test gates

We use a hardcoded string to describe the test image name.
A recent patch[1] changed the deployed image to
cirros-0.3.6-x86_64-disk. This change updates the hard-coded string.

A future patch may add this to configuration. This patch is to fix the
gate.
