service: place control command in subcgroup control/
Previously, we were brutally and onconditionally killing all processes in a service's cgroup before starting the service anew, in order to ensure that StartPre lines cannot be misused to spawn long-running processes. On logind-less systems this has the effect that restarting sshd necessarily calls all active ssh sessions, which is usually not desirable. With this patch control processes for a service are placed in a sub-cgroup called "control/". When starting a service anew we simply kill this cgroup, but not the main cgroup, in order to avoid killing any long-running non-control processes from previous runs. https://bugzilla.redhat.com/show_bug.cgi?id=805942
