Adding gitlabMergeRequestTargetProjectId variable

[tomasbjerre]

The project ID is needed when using the GitLab rest API to get information about the merge request.

@omehegan Tell me if there is anything unclear here.

I really need this in order to use https://github.com/jenkinsci/violation-comments-to-gitlab-plugin

@tomasbjerre thanks! This looks pretty straightforward. I normally merge small PRs like this in groups and do a release. I will try to do one in the next few days.

You forgot to edit MergeRequestHookTriggerHandlerImpl
and add .withMergeRequestTargetProjectId(hook.getObjectAttributes().getTargetProjectId())
after .withMergeRequestIid(hook.getObjectAttributes().getIid())

Fixed

This was released today in version 1.4.6 of the plugin.
