The script gate_hook.sh was removed at Zun side [1] as part of the effort for migrating to zuul v3 native job. However, zunclient still need this script and the removal causes the failure of the CI. This patch re-introduce the script at zunclient as a temporary fix. The long-term fix is to migrate the job to zuul v3 native as well.
