Ensure Jenkins integration is properly supported by GitLab
Current integration between GitLab and Jenkins relies on the GitLab Plugin: https://github.com/jenkinsci/gitlab-plugin
The team that was working on it is going to mostly give up, because the people are changing job and they cannot support it anymore. We were contacted about that, but I don't know if this information is public or not (so the confidential issue). We already considered to have this plugin "sponsored" or developed by GitLab, I think now it is time to take a decision on that.
We probably want also to include functionalities from https://github.com/jenkinsci/gitlab-plugin, since customers are asking about that.
