Jenkins CI Service doesn't send X-GitLab-Event header
I'm the new lead maintainer of the Jenkins gitlab-plugin. Within the last weeks I did a major code cleanup. After this change the plugin requires the
X-GitLab-Event header to determine the type of the webhook (push, merge, ...). Unfortunately this is just sent by webhooks not by the Jenkins Ci Service. Would be nice if you could add this functionality also to this service otherwise I have to add a ugly workaround to the gitlab-plugin.
