[aur-general] Dropping official gitlab packages

Hi guys, I maintain the official gitlab packages gitlab, gitlab-gitaly, gitlab-runner, gitlab-shell, gitlab-workhorse and python-gitlab. Out of these, I'll be dropping gitlab, gitlab-gitaly, gitlab-shell and gitlab-workhorse because they are way too much work to maintain and I can't keep up and the result isn't great. Currently known bugs: https://bugs.archlinux.org/task/62837 https://bugs.archlinux.org/task/63679 https://bugs.archlinux.org/task/63688 https://bugs.archlinux.org/task/63935 https://bugs.archlinux.org/task/63950 https://bugs.archlinux.org/task/64337 https://bugs.archlinux.org/task/64887 Unless any other masochistic TU really wants to feel the pain, I'll be dropping them in about two weeks.
