core,systemctl: add bus API to retrieve processes of a unit
This adds a new GetProcesses() bus call to the Unit object which returns an array consisting of all PIDs, their process names, as well as their full cgroup paths. This is then used by "systemctl status" to show the per-unit process tree. This has the benefit that the client-side no longer needs to access the cgroupfs directly to show the process tree of a unit. Instead, it now uses this new API, which means it also works if -H or -M are used correctly, as the information from the specific host is used, and not the one from the local system. Fixes: #2945
