[JENKINS-21573] Make possible to manually trigger builds based on different than 'patchset-created' event type

We for example want to use Gerrit trigger also for triggering regular (not staging) builds when change is merged. It is possible, but if something goes wrong it is not possible to trigger such build manually.

We for example want to use Gerrit trigger also for triggering regular (not staging) builds when change is merged. It is possible, but if something goes wrong it is not possible to trigger such build manually.

The issue concerns manual triggering in the gerrit-trigger-plugin for event types other than patchset-created, including builds after a change is merged. Start by tracing the plugin's manual trigger and event-type handling; the payload names no files or tests. Done means the requested non-patchset build can be triggered manually and the behavior is covered by appropriate verification.
