Add condition for printing merge request urls
By default, the URL to view/create a merge request will be displayed on push. If, however, the GitLab API specifies that disable_printing_merge_request_link
is true, the link will not be printed.
See https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/9663
Note: it is safe to merge this code even before the above MR is merged into GitLab CE since it will fallback to the previous default behavior if the API is unavailable.
