at end goal i agree on this but this will skip all backup tests whihc are running fine,
so let's wait till we move those tests to cindet tempest plugin or run on other integrated
job etc.

Initially, I was on the side to test/run everything together but on second thought
and by seeing tempest-full unstable I agree with you to find some solution to make
integrated-gate template testing (tempest-full) more efficient and stable for each service.

neutron also face lot of test failure due to volume backup or image tests which definitely
not related to neutron and not worth to block neutron development for that.

I have added this topic in QA PTG etherpad to find the best possible solution.
