Merge branch 'ref-update-multiple-commits' into 'master'
Allow updating a branch by multiple commits
In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6130 we made
Repository#commit_with_hooks a bit too strict; it only allowed
updating a branch by one commit. It turns out there is a feature in
GitLab Enterprise Edition where we update by multiple commits.
This change makes that possible, adds tests, and renames the method to
the more appropriate 'update_branch_with_hooks'.
See merge request !6246
