Bug#803013: systemd should not destroy application created cgroups

Hello all,

It's an uphill battle indeed - the official and documented mechanism is to set
"Delegate=yes" in a unit which wants to do its own cgroup management.
Everything else is just a hack prone to bitrotting...

Like it apparently happened to the previous patch that we've been carrying for
three years already:

https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/debian/cgroup-don-t-trim-cgroup-trees-created-by-someone-el.patch

Seems this is not sufficient any more?
