Code review comment for lp:~sergio-j-cazzolato/qa-jenkins-jobs/adjust-performance-executions

I am trying to reduce the number of executions and jobs to make it easy to check and review.

As the priority 1 is to test unity8 deb mode:
  . I am running unity8 deb for zesty and xenial in all the models (some model could be removed in the future for xenial)
  . Running few with the snap version just to check everything is working properly, but those metrics are not gonna be shown in grafana.
