Merge branch 'remove-update-head' into 'master'

Remove the update-head command since GitLab doesn't use it anymore

It looks like we tend to remove commands that are not used by GitLab anymore (see gitlab-org/gitlab-shell!26) and the `update-head` command will soon be in that case (see https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3705), so I think we should remove it from here too.

Note: I'm setting this as a WIP to ensure this doesn't get merged since the GitLab MR is not merged at that moment.

See merge request !51
