There was previously no way to skip a job if the contents of a given patchset did not require it to be run. This meant that tempest jobs would run in response to patchsets that would not affect their execution, like those that only modified documentation or unit tests. This change introduces a 'skip-if' configuration option that allows jobs to be configured to not run when specified criteria are met. Change-Id: I9b261f03ec00426160d9396f3a20312e89b624d4
