This story is about making the same stress tests that were done in MGNLHOOK-32, but using a SaaS instance.

We will have to take into account for example to change some details, as the authentication method probably.

Improvement: we also need to improve the Genres app detection for the code implemented on MGNLHOOK-32, to make it work on local instances (dx-core-webapp, dev-webapp) and on SaaS instances without the need of changing the CSS selectors.
