API validaton exemption for Danube-based releaseovp.1.1.0

This patch adds the ability to Dovetail to disable strict API
response validation in Tempest-based test cases run by Functest. This is
a backport of the changes from master, targeting OVP 1.0.1

Corresponding updates of the web portal will follow.
