[DRE-maint] Bug#909630: initscript found

[Luke Kenneth Casson Leighton]

https://gitlab.com/gitlab-org/gitlab-ce/raw/master/lib/support/init.d/gitlab

this is semi-suitable: at least it has been possible to get things up
and running, by removing the section starting "Script variable names"
and relying on the entries in /etc/default/gitlab that are absolutely
fine in the debian package

please for goodness sake do not assume that absolutely everyone is
happy to be forced to use systemd, it's incredibly unethical.

plus, sysvinit is still a legitimately-installed and supported *and
commonly-used" debian package.
